Sheena can row a boat at 3.0 mi/h in still water. She needs to cross a river that is 1.20 mi wide with a current flowing at 1.60 mi/h. Not having her calculator ready, she guesses that o go straight across, she should head 60.0° upstream.
c) How far upstream or downstream from her starting point will she reach the opposite bank?
d) IN order to go straight across, what angle upstream should she have headed?
