It’s the Friday Puzzle!


Here is a lovely puzzle sent to me by Ashley F.  Solution on Monday.

Imagine the Earth is perfectly circular and has a circumference of 24,000 miles.  If you had a piece of rope stretched around it, touching the floor, that rope would also be 24,000 miles long. If you were to add 3 feet to that rope and then make it hover above the ground until it’s a perfect circle again, approximately how far off the ground would it get?

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.
