Answer 2

Problem Analysis

We are given that a boat travels from point A to point B on a river in 2 hours, and returns from point B to point A in 3 hours. We need to determine how long it will take for the boat to travel the same distance from point C to point D, which are located on a lake.

Solution

To solve this problem, we need to make a few assumptions: 1. The speed of the boat remains constant throughout the journey. 2. The distance between points A and B is the same as the distance between points C and D.

Since the speed of the boat remains constant, we can use the formula:

Speed = Distance / Time

Let's assume the distance between points A and B (and also between points C and D) is represented by 'd'. We can calculate the speed of the boat using the given information:

Speed from A to B = d / 2

Speed from B to A = d / 3

Since the speed remains constant, we can equate the two speeds:

d / 2 = d / 3

To solve for 'd', we can cross-multiply and solve the equation:

3d = 2d

d = 0

This means that the distance between points A and B (and also between points C and D) is zero. However, this doesn't make sense in the context of the problem. It is possible that there is an error in the given information or the problem statement.

Without additional information, it is not possible to determine the time it will take for the boat to travel from point C to point D.
