Question

A man swims in a river with and against the water at a rate of 15m/s and 5m/s resp.Find the mans velocity in still water and the velocity of the river

Answer 1

Answer:

10 m/s is the velocity of man in still water and the velocity of the river is 5m/s.

Explanation:

Consider the velocity of man in still water as x and that of river as y

Then, according to the given conditions,

x + y = 15 ..... 1

x - y = 5 ...... 2

adding both the equations we get,

2x = 20

=> x = 10m/s

putting x = 10 in eqn 1 we get

y = 5m/s
