The boat is moving down the river at a speed of 18 km / h. How fast would this boat move in still water if the speed of the river is 3 km / h?
The speed of a boat down a river consists of the boat’s own speed and the speed of the river. Since we know the speed of the river flow and downward movement of the boat, we will find our own speed of the boat: 18 – 3 = 15 km / h.
In stagnant water, the boat moved only at its own speed, a speed of 15 km / h.
