Two buses left two points towards each other at the same time. The speed of one of them is 40 km / h

Two buses left two points towards each other at the same time. The speed of one of them is 40 km / h, and the speed of the other is 50 km / h. How many kilometers will the buses get closer in 1 hour? What is the distance between them in 3 hours, if the distance between the points is 560 km?

Let’s find the speed of convergence:

40 + 50 = 90 km / h.

Then in 1 hour they will get closer to:

90 * 1 = 90 km.

After 3 hours between them there will be:

560 – 3 * 90 = 560 – 270 = 290 km.
