A palindrome is a number or word that reads the smae backwards as it does forwards. 606, 4334, racecar, and the sentence "mr owl ate my metal worm" are palindromes.
While driving his car, Bob(so much of a palindrome lover that he changed his name from John to Bob) observes that the odometer reading forms a palindrome. It displays the milage 13,931. Bob keeps driving. Two hours later, he looks at the odometer again and, to his surprise, it displays a different palindrome
What is the most likley speed that bob is traveling?
