On the way from point A to point B the boat spent 40 minutes, and on the way back – 30 minutes, moving at the same own speed. In which direction does the river flow?
The speed of the boat when the river is moving is the sum of its own speed and the speed of the river. Accordingly, if the boat reached from point A to point B in 40 minutes, and back in 30 minutes, then the movement from point A to point B was slower. So the boat was moving against the current.
Answer: The river flows from point B to point A.
