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? |
2 kmph 3 kmph 4 kmph 5 kmph |
2 kmph |
(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 |
