Answer 1

To find the distance traveled by the steamboat in both directions, we can use the formula:

Distance = Speed x Time

Let's calculate the distance traveled by the steamboat in each direction.

Given Information:

- Time taken to travel downstream (with the current): 3 hours - Time taken to travel upstream (against the current): 3.9 hours - Speed of the steamboat: b km/h - Speed of the river current: n km/h

Distance Traveled Downstream:

The speed of the steamboat relative to the river current when traveling downstream is the sum of the steamboat's speed and the river current's speed. Therefore, the speed of the steamboat when traveling downstream is (b + n) km/h.

Using the formula Distance = Speed x Time, we can calculate the distance traveled downstream:

Distance downstream = (b + n) x 3 km

Distance Traveled Upstream:

The speed of the steamboat relative to the river current when traveling upstream is the difference between the steamboat's speed and the river current's speed. Therefore, the speed of the steamboat when traveling upstream is (b - n) km/h.

Using the formula Distance = Speed x Time, we can calculate the distance traveled upstream:

Distance upstream = (b - n) x 3.9 km

Therefore, the distance traveled by the steamboat downstream is (b + n) x 3 km, and the distance traveled by the steamboat upstream is (b - n) x 3.9 km.

Please provide the values of 'b' and 'n' so that I can calculate the distances for you.
