The distance between stations A and B is 165 km. From these stations, two trains leave at the same time towards each other and meet each other after 1.5 hours for a ride, which is located 90 km from station A. How fast do the trains travel? 1) What is the speed of the convergence of trains? 2) what is the speed of the train following from station A 3) What is the distance from station B to the meeting point 4) What is the speed of the train following from station B

The train traveling from station A traveled 90 km in 1.5 hours, therefore the speed of 1 train is VA = 90 / 1.5 = 60 km / h
The train traveling from station B traveled 165 – 90 = 65 km in 1.5 hours, hence the speed of the second train
VВ = 65 / 1.5 = 43.3 km / h
1) speed of convergence of trains 43.3 + 60 = 103.3 km / h
2) VA = 60 km / h
3) the distance from the meeting point to the station B = 65 km
4) train speed VB = 43.3 km / h
