Two buses left at the same time towards each other. Of the two cities, the distance

Two buses left at the same time towards each other. Of the two cities, the distance between which is 600 km, the speed of the first bus is 56 km / h, how fast the second bus was traveling if, 3 hours after leaving, the distance between them became equal to 240 km.

1) Let’s calculate the distance covered by two buses in 3 hours: 600 – 240 = 360 (km);
2) Find out the part of the route that the first bus covered in 3 hours: 56 • 3 = 168 (km);
3) Determine the part of the route that the second bus traveled in 3 hours: 360 – 168 = 192 (km);
4) Let’s calculate the speed of the second bus: 192: 3 = 64 (km / h).
Answer: the second bus was traveling at a speed of 64 km / h.
