Answer: train B will catch up train A in 25%2F60 hours = 2 hours and 5 minutes.

Step-by-step explanation:The train A is 50%2A%2825%2F60%29 miles = 1250%2F60 miles = 2050%2F60 miles = 205%2F6 miles ahead, when the train B starts his move.

The relative speed (B relative A) is 60 - 50 = 10 mph.

So, train B diminishes the distance between them at the rate of 10 mph.
