Two trains move from two cities towards each other at speeds of 60 km / h and 80 km / h.

Two trains move from two cities towards each other at speeds of 60 km / h and 80 km / h. At what distance from each other trains a) in 1 hour e meeting b) in 2 hours e meeting.

1. Since the trains move towards each other, therefore, they move closer together. We find out the speed of the convergence of trains, if it is known that one travels at a speed of 60 km per hour, and the second is 80 km per hour.
80 + 60 = 140 km per hour.
Therefore, 1 hour before the meeting, there will be a distance of 140 km between trains.
2. Find out what the distance between trains will be 2 hours before the meeting.
140 * 2 = 280 km.
Answer: 1 hour before the meeting between trains will be 140 km, 2 hours before the meeting 280 km.
