Two trains left the same station simultaneously in opposite directions. The speed of one of them is 50 km / h, and the speed of the other is 85 km / h. In how many hours will there be 540 kilometers between trains?

Let’s find the speed with which the train data is moving away from each other.
According to the condition of the problem, the speed of the first train is 50 km / h, and the speed of the second train is 85 km / h.
Since the trains go in opposite directions, the speed at which these trains move away from each other is equal to the sum of their speeds and is 50 + 85 = 135 km / h.
Consequently, the time interval after which the distance between the trains will be 540 km is equal to this distance divided by the speed of the trains’ removal and is 540/135 = 4 hours.
Answer: in 4 hours.
