Problem 856
Daily Math Challenge - January 06, 2023
You decide to take a drive in your car when you notice that the odometer reads 13931 miles. You smile because the mileage is a palindrome, a number that reads the same forward as it does backards. One and one-half hours later you notice that the odometer displays a different palindrome. What is the most likely average speed at which the car has been traveling?
