A swimmer heads directly across a river, swimming at 1.10 m/s relative to still water. He arrives at a point 50.0 m downstream from the point directly across the river, which is 75.0 m wide. What is the speed of the river current?What is the swimmer's speed relative to the shore? In what direction should the swimmer head so as to arrive at the point directly opposite his starting point? Express your answer in terms of the angle with respect to a line drawn directly across the river.
