A man rows to a place 48 km distance and back in 14 hours. He finds that he can row 4 km with the stream in the same time as 3 km against the stream. The rate of the stream is:

🧠 Explanation:

A man rows 48 km and back in 14 hours, with 4 km downstream equaling 3 km upstream in time. The stream’s rate is 1 km/h. Solve: let man’s speed be x, stream’s y. Then, 4/(x+y) = 3/(x-y), and total time gives y = 1. This teaches algebra for motion problems.
