Question:

A boat goes 8 km downstream in one hour and goes 2 km against the stream in one hour. Find the velocity of the stream.

Options:

2 km/h

3 km/h

5 km/h

4 km/h

Correct Answer:

3 km/h

Explanation:

(D.S) Downstream speed = 8 km/hr.

(U.S) Upstream speed = 2 km/hr.

Speed of stream = \(\frac{D.S - U.S}{2}\) = \(\frac{8 - 2}{2}\) = 3 km/hr.
