The speed of one train is 50 km / h and the other is 66 km / h after how long after the start of movement the distance between trains is 726 km.

1) Determine the speed at which the trains will move away from each other.
To do this, we summarize the speed of the first and second trains.
Will be:
50 + 66 = 116 km / h.
2) Find the distance time.
To determine the time it takes between trains to be 726 km, you need to divide the indicated distance by the speed of the trains moving away.
As a result, we get:
726/116 = 6.25 hours.
Answer: the indicated distance will be between trains in 6.25 hours.
