The boat moves down the river at a speed of 18 km / h. With what speed would this boat move in still water if the speed of the river flow is 3 km / h?
According to the laws of physics, water flows from top to bottom. This means that our boat is moving along the river.
From this we can conclude that its speed will be greater than its speed in still water by the speed of the river flow:
1) 18 – 3 = 15 (km / h) – speed of the boat in still water.
Answer: 15 km / h
