| From two points A and B, the distance between which is 2720 km, two trains left at the same time to meet each other and met in 20 hours. Find speed II, if I covered 304 km for every 4h.
Let’s find the speed of the first train. Let’s divide the distance – 304 kilometers by the time – 4 hours:
304: 4 = 76 kilometers per hour.
The speed of the first train is 76 kilometers per hour.
Let’s find the distance that he traveled in 20 hours:
76 * 20 = 1520 kilometers.
Let’s find the distance traveled by the second train:
2720 – 1520 = 1200 kilometers.
Let’s calculate the speed of the second train:
1200: 20 = 60 kilometers per hour.
The speed of the second train is 60 kilometers per hour.
Answer: the speed of the second train is 60 kilometers per hour.
