At 14 h, a train left the station at a speed of 80 km / h, and an hour later the second train left the station at a speed of 75 km / h.

At 14 h, a train left the station at a speed of 80 km / h, and an hour later the second train left the station at a speed of 75 km / h. What is the distance between trains at 17 o’clock on the same day?

1) 17 – 14 = 5 (h) – the first train was traveling
2) 80 ◦ 5 = 400 (km) – the first train passed
3) 5 – 1 = 4 (h) – the second train was traveling
4) 75 ◦ 4 = 300 (km) – the second train passed
5) 400 – 300 = 100 (km)
Answer: 100 km
