A river 93.2 m wide flows toward the south at 32.4 m/min. A girl on the west bank wishes to reach the east bank in the least possible time. She can swim 93.2 m in still water in 1.95 min.

(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?

Thomas and Ashley are swimming in a river which is 15 m wide. Both swim with a speed u = 1.2 m/s relative to the water, which is flowing downstream at a speed v = 0.25 m/s. They both leave a point on one bank at the same time. Thomas swims directly upstream a distance 15 m, then turns back and swims downstream to his starting point. Ashley points herself so that, taking account of the current, she can swim...
