| **Two trains departed from the station simultaneously in opposite directions; the first train was traveling at a speed of 83 kilometers per hour and the second, 72 kilometers per hour, how many hours would the distance between them be 1395 km?**

Since the trains went in opposite directions, then the speed of their distance from each other will be equal to the sum of their speeds.

We get:

83 + 72 = 155 km / h.

Time is the ratio of the distance to the speed of movement, therefore, in order to find in how many hours the indicated path will be between them, we divide 1395 km by 155 km / h.

As a result, we get:

1395/155 = 9 hours.

Answer:

1395 km will be between trains in 9 hours.
