Swimmer and River (Relative Velocity)

1. The problem statement, all variables and given/known data
A swimmer is to reach at a point 30 degree upstream on the other side of a river flowing with velocity 5 m/s. The velocity of the swimmer w.r.t. water is $$5\sqrt{3}$$. The swimmer should steer at an angle??

3. The attempt at a solution

I am unable to guess the scenario. What does this mean?

Hi ritwik06!

It just means where the line at 30º to straight-across hits the other bank.

(so straight-across would be 0º upstream)
