The speed of the ship in still water is 27 km / h, and the speed of the river is 3 km / h.

The speed of the ship in still water is 27 km / h, and the speed of the river is 3 km / h. The route of the ship along the river in 2 hours?

Let’s imagine how a motor ship moves along the current. We will see that both the ship and the river move in the same direction. This means that in order to determine the speed of the ship along the river, you need to add the speed of the ship in still water and the speed of the river.

We add:

27 + 3 = 30 km / h – speed of the motor ship downstream.

Let’s determine the distance that the motor ship has covered in 2 hours. To do this, multiply the speed of the ship by 2:

30 * 2 = 60km.

Answer: in 2 hours the ship covered 60 kilometers along the river.
