A man can row 32 km in 4 hours along the stream and can cover the same distance in 8 hours against the water. Find the speed of stream?
Answer & explanation
Correct answer: option 1
(D.S) Downstream speed = \(\frac{32}{4}\) = 8 km/hr
(U.S) Upstream speed = \(\frac{32}{8}\) = 4 km/hr
Speed of stream = \(\frac{D.S - U.S}{2}\) = \(\frac{8 - 4}{2}\) = 2 km/hr
