The distance between the two cities is 194.5 km at the same time from these cities two trains left towards each other, one with a speed of 1.1 km / min, the other with a speed of 1.85 km / min. What is the distance between the trains in 0.25 h?

We translate the specified time from hours to minutes.

Since there are 60 minutes in 1 hour, then 0.25 hours will be equal to:

0.25 * 60 = 15 minutes.

Let’s find the speed with which the trains were moving towards each other.

Let’s add the speed of the second to the speed of the first train.

1.1 + 1.85 = 2.95 km / min.

Let’s find the distance that trains will approach in a given time.

Multiply 15 minutes by the rendezvous speed.

15 * 2.95 = 44.25 km.

We find the distance between trains at a given time.

194.5 – 44.25 = 150.25 km.

Answer: 150.25 km.
