A river flows due south with a speed of 4.00 m/s. A man steers a motorboat across the river; his velocity relative to the water is 3.80 m/s due east. The river is 790 m wide. How much time is required for the man to cross the river? (Express your answer in seconds.) How far south of his starting point will he reach the opposite bank? (Express your answer in meters.)
