Mr. P was driving in his Outback on I-25 when he noticed the odometer read 24,942 miles.
Being a mathematician, Mr. P observed that it was a palindrome, and then of course, he wondered when the next time the odometer would be a palindrome.
He didn't have to wait long because an hour and forty minutes later, the odometer showed a new palindromic number.
How fast was Mr. P driving in that hour and forty minutes?
Solution to the Problem:
The answer is 66 mph.The next palidrome after 24942 is 25052. So, Mr. P had traveled 110 miles in the hour and 40 minutes.
Divide 110 by 5/3 hours to get 66 mph.
