From two stations, the distance between which is 30 km, two trains depart simultaneously in opposite directions, moving away from each other. one goes at a speed of 55 km / h, the other at 70 km / h. What is the distance between them: a) after 1 hour; b) after 3 hours.

The solution of the problem:
1. To solve the problem, we find the speed of removal of two trains in one hour.
55 + 70 = 125 kilometers.
2. Find out what the distance will be between trains in an hour.
30 + 125 = 155 kilometers.
3. Find how many kilometers the trains will pass in 3 hours.
125 * 3 = 375 kilometers.
4. Let’s calculate how many kilometers will be between trains in 3 hours.
375 + 30 = 405 kilometers.
Answer: In an hour the distance between trains will be one hundred and fifty-five kilometers, and in three hours four hundred and five kilometers.
