The difference in time is 30 minutes. In 30 minutes, or one-half hour, Train A will travel 20 miles. The difference in the speeds is 8 miles per hour. How long would it take train B to go 20 miles at 8 miles per hour? Add that amount of time to 11:55 PM.

Train A has a 20 mile lead.
Overtake speed is 8 mph
20/8=2.5 hrs
11:55+2:30=2:25 am
