The distance between the stations and AB is 165 km. From these stations, two trains leave at the same time

The distance between the stations and AB is 165 km. From these stations, two trains leave at the same time towards each other and meet after 1.5 hours at the junction, which is located 90 km from the station. How fast do the trains travel?

Let’s find the distance that the second train travels to the siding:

165 – 90 = 75 km.

Since the travel time is the same, the train speeds will be equal:

90: 1.5 = 60 km / h;

75: 1.5 = 50 km / h.

Answer: trains move at speeds of 60 and 50 km / h.
