Two trains left the two cities at the same time towards each other. one train was traveling at a speed of 75 km / h. What was the speed of the second train if the distance between the cities was 556 km, and the trains met in 4 hours?

Let’s find the distance in 4 hours, that is, before the meeting, the first train passed:
75 * 4 = 300 km.
Based on this, you can find the path traveled by the second train. To find it, you just need to subtract this distance from the total distance between cities:
556 – 300 = 256 km.
Now let’s find the speed of the second train using the formula:
v = S / t, where S is the distance traveled by the train; t is the time during which he traveled this distance.
Substitute the known values:
v = 256/4 = 64 km / h.
Answer: the speed of the second train is 64 km / h.
