John Wick is planning on crossing a river. He wants to get to a landing dock directly North across the river. The current in the river runs 0.5m/s from west to east. a) If Mr. Wick can swim at 1.5m/s in still water, what direction should he point to get to the dock? (Include an angle) b) It takes Mr. Wick 5 min to complete his crossing of the river. How far directly across is the river at this point? Include diagrams
