Two trains A and B are going in the same direction with the speeds of 20 km/h and 15 km/h respectively. If the starting point of B is 200 km ahead from the starting point of A, how long will it take A to meet with the train B?

Relative speed of train A with respect to B = 5 km/h
Distance to be covered = 200 km
Time taken = $$\frac{200}{5}$$ = 40 h
