Question 1094250: The odometer of a family car shows 15,951 miles. The driver noticed that this number is palindrome: it reads the same backward as forward. Surprised, the driver saw his third palindromic odometer reading (not counting 15,951) exactly five hours later. How many miles per hour was the car traveling in those 5 hours (assuming speed was constant)?

Next palindrome after 15,951 is 16,061. The 2nd is 16,161. 
That's a distance of 210 (16,161 - 15,951) miles in 5 hours, and an average speed of highlight_green%28matrix%281%2C2%2C+42%2C+mph%29%29.
