A river flows due south with a speed of 1.70 m/s . A man steers a motorboat across the river; his velocity relative to the water is 4.40 m/S . The river is 800 In wide. In which direction should the motorboat head in order to reach a point on the opposite bank directly east from the starting point? (The boat's speed relative to the water remains 4.40 m/s .)
