Question 628562: Elaine is fond of making a wish everytime her car's adometer displays a number read the same forward and backward. At 10:18am the adometer read 87978 km. Traveling continuously the adomater displayed the next possible number that read the same forward and backward at 11:13am. During this time, what was the car's average speed in kilometers per hour?

There are no more such numbers before 88000 km
After 88000, the next one is 88088 km
The km traveled is km
and
11:13 minus 10:18 is 42 minutes plus 13 minutes
equals 55 minutes
55 minutes is hours
km/hr
Hope I got it
