Two trains left the same city at the same time in opposite directions from 5 hours were at a distance of 650 km from each other.

Two trains left the same city at the same time in opposite directions from 5 hours were at a distance of 650 km from each other. What is the speed of the second train if the speed of the first is 62 km / h.

Let’s calculate how many kilometers the distance between the first and second trains increased every hour, if we know, based on the conditions of this task, that in 5 hours it reached 650 kilometers:
650: 5 = 130.
Let’s calculate at what speed the second train moved away from the first train, if we know, based on the conditions of this task, that the speed of the first train is 62 km / h:
130 – 62 = 68.
Answer: The speed of the second train under such conditions was 68 km / h.
