Answer 3

Problem Analysis

To determine the direction of the river, we need to analyze the time it takes to travel from point A to point B and back. If the time taken to travel downstream (from A to B) is greater than the time taken to travel upstream (from B to A), it means that the river is flowing in the direction from A to B. Conversely, if the time taken to travel upstream is greater, it means that the river is flowing in the opposite direction, from B to A.

Solution

Given that the time taken to travel from point A to point B is 40 minutes and the time taken to travel from point B to point A is 30 minutes, we can compare these times to determine the direction of the river.

- If the time taken to travel downstream (from A to B) is greater than the time taken to travel upstream (from B to A), it means that the river is flowing in the direction from A to B. - If the time taken to travel upstream is greater than the time taken to travel downstream, it means that the river is flowing in the opposite direction, from B to A.

In this case, since the time taken to travel from A to B is 40 minutes and the time taken to travel from B to A is 30 minutes, we can conclude that the river is flowing from point A to point B.

Answer

The river is flowing from point A to point B.
