7) The water in a river flows uniformly at a constant speed of 2.50 m/s between parallel banks 80.0 m apart. You are to deliver a package across the river, but you can swim only at 1.50 m/s. a) If you choose to minimize the time you spend in the water, in what direction should you head? b) How far downstream will you be carried? c) If you choose to minimize the distance downstream that the river carries you, in what direction should you head? d) How far downstream will you be carried? (a: straight across, b: 53.3 s and 133 m downstream, c: 36.9 degrees, 107 m)
