Two motor ships departed from the two quays simultaneously in opposite directions. When one of them covered 180 km at a speed of 30 km / h, the distance between the ships became 348 km. At what speed was the other ship going?

Knowing the path and speed of the ship, we will find the time that this ship has spent on overcoming this path: 180: 30 = 6 hours.

Let’s find the path length of the second motor ship.

348 – 180 = 168 km.

Knowing the path and the time taken to overcome it, we will find the speed of another motor ship:

168: 6 = 28 km / h.

Answer: The speed of the other ship is 28 km / h.
