Question

A river is flowing with a speed of 1 m/s. A swimmer wants to go to point C starting from A. He swims with a speed of 5 m/s, at an angle q w.r.t. river flow. If AB = BC = 1000 m. Then the value of q is

Answer 1

Now it is given that the velocity of the river which is flowing in the horizontal direction is 1Km/hr. And the velocity of a swimmer is 5Km/hr. So, V = 5Km/hr. The total velocity in the horizontal direction = velocity of river + component of velocity of swimmer in horizontal direction.
