A driver notches up 15951 miles on his milometer and realises that this number is palindromic. He is quite surprised at this, but is doubly so when 2 hours later he reads another palindromic number from his milometer. How fast was he going in those 2 hours?
This is an unusual paragraph. I'm curious how quickly you can find out what is so unusual about it? It looks so plain you would think nothing was wrong with it! In fact, nothing is wrong with it! It is unusual though. Study it, and think about it, but you still may not find anything odd. But if you work at it a bit, you might find out! Try to do so without any coaching!
