Two ships sailed simultaneously from the pier in one direction. The speed of the first ship is 25 km / h

Two ships sailed simultaneously from the pier in one direction. The speed of the first ship is 25 km / h. After 5 hours, the distance that the second ship passed was 4/5 of the distance that the first ship passed. Find the speed of the second ship.

1) 25 ◦ 5 = 125 (km) – the first passed
2) 125: 5 ◦ 4 = 100 (km) – the second passed
3) 100: 5 = 20 (km / h) – the speed of the second
Answer: 20 km / h
