# Distance between cities is 980 km. The first 4 hours the train went at an average speed of 80 km / h

Distance between cities is 980 km. The first 4 hours the train went at an average speed of 80 km / h. With what average speed did the train cover the rest of the way if it took 6 hours?

1) Find the distance that is the first part of the journey covered by the train in 4 hours. To find the path traveled, you need to multiply the speed by time. S = v * t.

80 * 4 = 320 (km).

2) Find the distance that is the second part of the path covered by the train.

980 – 320 = 660 (km).

3) Let’s find the speed with which the train was moving on the second section of the track. To find speed, you need to divide the distance by the time. v = S: t.

660: 6 = 110 (km / h).

Answer. For the second part of the journey, the train moved at a speed of 110 km / h.
