Two trains departed from one station simultaneously in opposite directions, the speed of one of them being 54 km / h and the speed of the other is 18 km / h more after how many hours the distance between them will be equal to 504 km.

To begin with, let’s find out the speed of the second train, if it is known that its speed is 18 km / h more than the speed of the first train (54 km / h). To do this, perform the following action:

54 + 18 = 72 km / h – the speed of the second train.

Now let’s calculate at what distance the trains will be in 1 hour. In this way,

54 + 72 = 126 km – the distance between trains in 1 hour.

Next, we will find out after what time there will be 504 km between them. Means,

504 ÷ 126 = 4.

Consequently, in 4 hours the distance between trains will be 504 km.
