Question

A man can row downstream 20 km 2 hours and upstream 4km 2 hours. what will be the speed of rowing in still water​

Answer 1

Answer:

6 kmph

Step-by-step explanation:

Distance = Speed * time

speed of rowing in still water,u =

$\frac{downstream \: speed \: + upstream \: speed \: }{2}$

Downstream speed = 20/2 = 10 kmph

Upstream Speed = 4/2 = 2 kmph

u = 12/2 = 6 kmph

Speed of rowing in still water = 6 kmph
