From two stations, the distance between which is 40 km simultaneously in opposite directions, moving away from each other, two trains departed the speed of the first 60 km / h of the second 70 km h what is the distance between the trains a) after 2 hours b) after 5 hours

1. Let us find the speed of convergence of trains, if it is said that the speed of the first train is 60 kilometers per hour, and the speed of the other train is 70 kilometers per hour.

60 + 70 = 130 kilometers.

2. Determine the distance that will be between trains in 2 hours.

40 + 130 = 170 kilometers.

3. Let’s calculate how many kilometers will be between them in 5 hours.

5 * 130 + 40 = 690 kilometers.

Answer: In 2 hours the distance between trains will be 170 kilometers, and in 5 hours 690 kilometers.
