A river 98.2 m wide flows toward the south at 35.8 m/min. A girl on the west bank wishes to reach the east bank in the least possible time. She can swim 98.2 m in still water in 1.90min.
(a) How long does it take her to cross the river?
(b) How far downstream does she travel?
(c) What is her velocity relative to land?
magnitude
direction south of east
(d) What is the total distance she travels?
(e) In what direction must she swim if she wishes to travel straight across the river?
