Answer to the Friday Puzzle….

55

cover

On Friday I posted these puzzles…..

– My house is the fourth house away from one end of the street and the ninth house away from the other end of the street.  How many houses are there in the street?

– Points A and B are 100 miles apart.  A car leaves A at the same time as a bike leaves B.  The car travels at 40 mph whilst the bike travels at 10 mph.  Which is further from A when they pass?

If you have not tried to solve them, have a go now.  For everyone else, the answers are after the break.

The answer to the first puzzle is 15, and in the second one the car is 15 miles from A whilst the bike is 30 miles away.  Did you solve them? Any other answers?

UPDATE: OK, so that was an April Fool’s joke.  The correct answers are that there are 12 houses in the street, and that they will be same distance from A.

I have produced an ebook containing 101 of the previous Friday Puzzles! It is called PUZZLED and is available for the Kindle(UK here and USA here) and on the iBookstore (UK here in the USA here). You can try 101 of the puzzles for free here.

    In Q2, aren’t they both the same distance from any point when they meet?

    • Rock but not Roll says:

      For electronic archeologists here is Richard’s original and incorrect answer.

      As he so often provides wrong answers we can not be sure if his errors were due to it being April Fools’ Day (in some cultures) or general incompetence:-

      “The answer to the first puzzle is 15, and in the second one the car is 15 miles from A whilst the bike is 30 miles away. Did you solve them? Any other answers?”

    Surely there are 12 houses and they are the same distance from A since they are passing they are st the same point.

  3. simontaylor says:

    Huh? Maybe something to do with the date today, but surely when the car and the bike pass, they are BOTH the same distance from A, because they are at the same place? It makes no difference what speed they are travelling at. I’ve only just woken up, so maybe lining myself up for a fall here…😉

    • Natura Umana says:

      You are probably wright. The answers today have something to do with april first.

    • Stevie says:

      When the two meet they are the same distance from A but when they pass, which is the instant after they meet, the bicycle is closer to A.
      Great April Fool answer!

  4. Natura Umana says:

    I found different answers:
    first : there are 12 houses on the street (9+4 = 13 – 1 ) since my house is the same in both exeamples.
    second : in the moment they pass each other they are at the same distance from point A.
    i tought it was a trick question.

  5. Andy says:

    I got 12 houses and they are the same distance from A. Hmmmm..!

  6. Andy says:

    D’Oh! Of course… today’s date.

    I’m so annoyed with myself I missed that one.

    • mikekoz68 says:

      They are the same distance from “A” when they MEET but when they PASS, then the car is slightly furthur from “A”. So answers are 12 and the car, unless there’s more April Fool’s stuff goin on

  7. Anonymous says:

    Come on people, look at the date !!

  8. Anonymous says:

    I concur with Rob; bike and car are equidistant from A when they meet.

    Also, Q1, I don’t understand why there aren’t 12 houses (on my side) of the street. Where do you get 15 from?

  9. Paul says:

    The answers are surely 12 (or 24 if we are counting both sides), and they are the same distance from A.
    Oh, and I think Richard is having some fun n April 1st! Too late here in Australia so the joke is on him.

  10. The Pick Man says:

    Good try, Richard. But it didn’t work. However, I enjoyed the joke.

  11. Dharmaruci says:

    often mr wiseman gets the puzzle wrong (by lose phrasing or typoisms), today he gets the ans wrong, april fool!

    • Dave says:

      As we’ve discussed, there’s rarely a problem with the puzzle, simply with your lack of reading comprehension and inability to follow simple instructions.

  12. Al says:

    Of course those are the ‘April Fools’ answers.

    The correct answers are:
    1. There are most likely* 24 houses on the street and you live at either number 7, 8 ,17 or 18.
    2. Both the car and the bike are the same distance from A ‘when they pass’.

    * I say most likely as you have to assume that there are odd and even sides to this street and that there are the same number of houses on both sides. If you change either of these assumptions you can come to a different answer.

  13. Well played, sir, well played🙂

  14. Martha says:

    Will the answnoon change at 12 noon?

  15. Bill says:

    Oh, very good.

  16. Davis says:

    “How many houses are there in the street?”

    Typically houses aren’t *in* the street, so I’m going with zero as the non-April Fool’s answer.

  17. The Masked Twit says:

    For question 1 I got 8 houses, 2 blocks of flats, 1 office block and one building site – that makes 12 lots in all, so I am not in accord with Richard (no change there).

  18. Anonymous says:

    What about houses on opposite side?

    • palomitaquince says:

      Who says that there are houses on the opposite side? May be there is a park, or a river or…

  19. Stephen says:

    I took the end of the street as meaning the road, not the last house, so my answer for 1 was 12. I also agree with others, that the bike and car must be the same distance from A, since they are passing each other.

  20. I guess it’s April fools- The houses depends if they’re counting both sides of street. The my house is number 9 and four so its 9+3=12, but if they only counted one side, then there’s 24 houses. In the second question, they will both be 80 miles from point A after 2 hours. I was only gotten by an April fool once this morning, when I was virtually still asleep.

  21. Tom says:

    Aren’t April Fool jokes supposed to be funny?

  22. dayuntoday says:

    I don’t think incorrect answers are a great joke. Waiting for the punchline, Richard.

  23. Anonymous says:

    Why does everyone get upset when they get “fooled” here?
    lol
    Lighten up peps!

  24. Evan Cohrs says:

    Your second question involving the car and bike is incorrect, in order to pass, they must be at the same point, so when they pass, they must be right next to each other, therefore, being the same distance from point A, which is 80 miles away, and would take two hours for both to meet. I’m sorry if I misread this, but I saw a trick question. Thank you.

  25. kaggyx says:

    I got 12 and for the second one i got the Car.
    Since it said when they pass each other so the Car is further once they pass.

    • Anders says:

      so the car instantaneously jumps 15 miles further the instant they have passed? In my opinion, Richard got it wrong, as so often before, and it has nothing to do with April 1.

      For the record, my answers were 12 (3+8) and “the same”

    • mikekoz68 says:

      I agree with “kaggyx” When they ‘meet’ they are the same distance from A but as they ‘pass’ then the car is definitely further, So Richard still got it wrong.

  26. Anders says:

    Argh, 13 houses, 3 on one side of the house, plus 8 on the other, plus the house itself

  27. Anders says:

    argh again, I shouldn’t post on holidays, 8+3 is not 12 in this universe. 8+3+1 is 12

  28. Brilliant. It took me a good 15 seconds to “get” the Monday Puzzle. 🙂

  29. Canadian Atheist says:

    Laugh – I nearly started
    That’s about as funny as Jimmy Saville in a children’s home Richard.

  30. Anonymous says:

    Actually, I would hope that there are zero houses *in* the street. 🙂

  31. Mark_D says:

    How could the date possibly affect the answers to these puzzles??!!, they didn’t even mention a date in them! Forget these stupid puzzles, UNSUBSCRIBE!

  32. Donald says:

    I hope that the houses “in” the “street,” are not blocking traffic!

  33. kateoz says:

    Re the first puzzle, I assumed there were 2 sides to the street, hence 24 (as others have said). I got both puzzles right, and when you’re right you know you’re right, so your April Fool thingy just perplexed me…but good try 🙂

  34. CAPE BRETONER says:

    (1) There are 24 houses “on” the street; 12 on each side. There would be no houses “in” the street, unless a horrible earthquake occured but wasn’t mentioned!!!……… (2) “When” they pass the car would be farther away as it is on the B side of the bike, while the bike is now closer to A as it is on the A side of the car. “When” they pass is quite different from “as” they pass. “As” they pass they are equidistant; but “when” they pass the bike is closer.

  35. vmos says:

    12? 15? Surely the answer is at least 24 or are there no houses on the opposite side of the street?

  36. Malky says:

    Assuming it is a normal street are there not 24 homes as they will be on both sides of the street?

  37. Eddie says:

    Enjoyed the April 1st joke. Nice one.

  38. Ron Murphy says:

    So, how many April Fools Fridays have we had this year? If we go by some of the puzzles it might be quite a few.

  39. bcollingwood says:

    24 houses on the street! Both sides of the road?

    • mikekoz68 says:

      Why? There could just as easily be a park, or nothing at all on the other side of the street.

    • bcollingwood says:

      Yeah you could be right! Although, we are left to speculate on this fact. It is more likely that there is two rows of houses on the street. Yet, these to not require to be in equal number so I understand the reason for not including them. It would satisfy my pedantic twitching if it was mentioned that only one side of the street was to be included… Sigh… I hate sucking all the fun out of things.

  40. I am actually grateful to the holder of this website who has shared this fantastic
