A car's odometer shows 72927 miles, a palindromic number. What are the minimum miles you would need to travel to form another?
A palindrome is a word (or in this case a number) which can be read forwards and backwards as the same word, such as kayak or 1221.
I'm posting one puzzle, riddle, math, or statistical problem a day. Try to answer each one and post your answers in the comments section. I'll post the answer the next day. Even if you have the same answer as someone else, feel free to put up your answer, too!

Some Quick Palindrome Math

The next one would be 73037, I would think. So, 110 miles?ReplyDelete
I got 110 too, is this correct?ReplyDelete
I believe so. 73,037 should be the next palindrome mile, so the car has to go 110 miles to get there.ReplyDelete
