Two trains are traveling on parallel tracks.

Train A is going 40 mph and Train B is going 48 mph.

Train A will pass the station at 5:20 p.m.

Train B will pass the same station at 5:35 p.m.

At what time will Train B catch up to Train A?

In the 15 mins from 520 to 535, train A goes 12 miles (48 x 1/4 hour)
Train B gains on train A at 8 mph (48-40)
12 miles/8 mph = 1.5 hours
535 + 130 = 7:05 PM
