Two electric trains departed from the railway station in opposite directions.

Two electric trains departed from the railway station in opposite directions. What is the distance between them in 10 minutes, if one electric train moves at a speed of 72 km per hour and the second 84 km per hour?

To complete this task, first of all, let’s convert minutes to hours. 1 hour = 60 minutes.

10 minutes = 10/60 = 1/6 hour.

Let’s calculate what distance the first train covered, knowing that it moves at a speed of 72 km / h.

s1 = 72 * 1/6 = 12 kilometers.

Let’s calculate the distance covered by the second train, knowing that it is moving at a speed of 84 km / h.

s2 = 84 * 1/6 = 14 kilometers.

Let’s calculate the distance between trains in 10 minutes.

12 + 14 = 28 km.

Answer: 28 km.
