Question

A man rows downstream 32 km and 14 km upstream .if he takes 6 hours to cover each distance then find the velocity of the stream​

Answer 1

The velocity (in km/h) of the stream is 1.5 Km/hr

Step-by-step explanation:

Down stream "d" = 32 /6 = 5.33 Km/hr

Speed = distance / time

Upstream "u" = 14/6 = 2.33 Km/hr

Speed of stream = 1/2 ( d - u)

                            = 1/2 ( 5.33 - 2.33)

                            = 1/2 x 3

                            = 1.5 Km/hr

Thus the velocity (in km/h) of the stream is 1.5 Km/hr
