Question

A man swims across a river which flows with a velocity of 3km/h due east .velocity of man relative to water is 4km/h due north then what is the velocity relative to the bank of the river

Answer 1

Answer:

Explanation:

Given A man swims across a river which flows with a velocity of 3km/h due east .velocity of man relative to water is 4km/h due north then what is the velocity relative to the bank of the river

Now we know that

The velocity of the man relative to bank of the river will be

v = √3^2 + 4^2

     = √9 + 16

      = √25

  v   = 5 km / hr

So  the velocity relative to the bank of the river will be 5 km / hr
