From two stations, which are at a distance of 652 km, two trains left at the same time towards each other and met in 4 hours. The speed of one train is 85 km / h. How fast was the other train going?

1) How many kilometers did the first train travel before meeting the second? To find the distance traveled, the speed must be multiplied by the travel time.

85 * 4 = 340 (km).

2) How many kilometers did the second train travel before meeting the first?

652 – 340 = 312 (km).

3) How fast was the second train moving? To find the speed, the distance traveled must be divided by the time.

312: 4 = 78 (km / h).

Answer. The second train was moving at a speed of 78 km / h.
