Too bad, the number on the picture is not a palindromic number.
Suppose the odometer of your car shows a palindromic number, say, 15, 951. And exactly two hours later, the odometer shows a new palindromic number.
What was the average speed of the car in those two hours?
The next Palindromic number would be 16061 a difference of 110 miles in 2 hours is an average speed of 55 mph.
ReplyDeleteHowever, if it was a super car it could have reached the next palindrome after that at 16161
or 210 miles in 2 hours at an average speed of 105 mph.
