A swimmer wants to cross a river, from point A to point B, as shown in the figure. The distance d1 (from A to C) is 200 m, the distance d2 (from C to B) is 150 m, and the speed vr of the current in the river is 5 km/hour. Suppose that the swimmer's velocity relative to the water makes an angle of θ=45degrees with the line from A to C, as indicated in the figure.
To swim directly from A to B, what speed us, relative to the water, should the swimmer have?
Express the swimmer's speed numerically, to three significant figures, in kilometers per hour.

A swimmer, capable of swimming at a speed of 1.90m/s in still water (i.e., the swimmer can swim with a speed of 1.90m/s relative to the water), starts to swim directly across a 1.93-km-wide river. However, the current is 1.24m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? (b) How far downstream will the swimmer be upon reaching the other side of the river?

A swimmer, capable of swimming at a speed of 1.02 m/s in still water (i.e., the swimmer can swim with a speed of 1.02 m/s relative to the water), starts to swim directly across a 2.96-km-wide river. However, the current is 0.550 m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? (b) How far downstream will the swimmer be upon reaching the other side of the river?
