A quick bit of good news before the puzzle. The Apple ipad launches today in the UK and 59 Seconds has been chosen as one of the very first featured ebooks! Congratulations to everyone at MacMillan for working so hard and making that happen.
OK, on with the puzzle.
The other day I went for a bike ride. My favourite route has signs every meter saying how far you have travelled. I came across the sign saying ‘15951 meters’ and thought ‘Oh, that’s interesting, it is a number palindrome because it reads the same from left to right as right to left’. Then I rode on. Two hours later I came across the next palindromic number sign. How fast was I going?
As ever, please do NOT post your answers, but do say if you think you have solved it and how long it took. Solution on Monday!
