Question

A boy Swims in the river with velocity 8 Kmph opposite to the river to the river flow of velocity 4 Kmph then the relative velocity man w.r.t river flow is....​

Answer 1

Hey there buddy! Here's your answer!

Answer:

12 kmph

Step by Step Explanation:

Let Vb and Vr be the velocity of the boy and velocity of the river respectively.

Then,

ATQ,

Vb= 8 kmph

Vr= - 4kmph(opposite direction)

Then

Relative velocity of man w.r.t. river flow is, Vbr

Now,

Vbr = Vb - Vr

= 8 - (- 4)

=12 kmph
