The water in a river flows uniformly at a constant speed of 2.53 m/s between parallel banks 69.8 m apart. You are to deliver a package directly across the river, but you can swim only at 1.74 m/s.

(a) If you choose to minimize the time you spend in the water, in what direction should you head? ____° from the direction of the stream

(b) How far downstream will you be carried? ______m

(c) If you choose to minimize the distance downstream that the river carries you, in what direction should you head? ____° from the direction of the stream

(d) How far downstream will you be carried? _____m

-----------------

I know we're dealing with motion in 2D, but I don't even know which equations to use or how to start. Any help or jumpstarts will be greatly appreciated.
