Problem Analysis

We are given the speed of a boat on a lake, which is 12 km/h. We need to find the time it takes for the boat to travel a distance of 17 km upstream against the current of a river. We are also given that the boat can cover this distance in 7 hours when moving downstream with the current.

Solution

To solve this problem, we can use the formula:

Time = Distance / Speed

Let's calculate the time it takes for the boat to travel 17 km upstream against the current.

Upstream Speed = Boat Speed - River Current Speed

From the given information, we know that the boat speed is 12 km/h. However, we don't have the river current speed. Therefore, we cannot calculate the exact time it takes for the boat to travel upstream without this information.

If you have any additional information or if there is anything else I can help you with, please let me know!
