An athlete crosses a 29 m wide river by swimming perpendicular to the water current at a speed of 0.6 m/s relative to the water. He reaches the opposite side at a distance 41 m downstream from his starting point.

(A) How fast is the water flowing relative to the ground?

(B) What is the speed of the swimmer with respect to a friend at rest on the ground?
