The train traveling from one city to another covered the first 180 km of track at a speed of 60 km per hour

The train traveling from one city to another covered the first 180 km of track at a speed of 60 km per hour, for the rest of the way it took it at the same speed for 4 hours more than how many kilometers did the train have to travel?

1) What is the speed of the train on the first section of the track? To find the speed, the distance traveled must be divided by the time. v = S: t.
180: 60 = 3 (h).
2) How long does it take for the train to cover the second section of the track?
3 + 4 = 7 (h).
3) What is the length of the second section of the train path? To find the path traveled, you need to multiply the speed by time. S = v * t.
60 * 7 = 420 (km).
4) How many kilometers should the train travel?
180 + 420 = 600 (km).
Answer. 600 kilometers.
