Question

17. A man rows downstream 32 km and 14 km upstream. If he takes 6 hours to cover each distance, then find the velocity (in kmph) of the current.​

Answer 1

Rate downstream = [32/6] kmph; Rate upstream = [14/6] kmph.

=> Velocity of current = 1/2[32/6 - 14/6] kmph

                                 = 3/2 kmph

                                 = 1.5 kmph
