Suppose that the swimmer in the figure below has a swimming speed relative to the water of 0.45 m/s, while the speed of the current is 2.0 m/s. If it takes the swimmer 160 s to cross the river, how wide is the river?

As long as the swimmer is perpendicular to the river, the speed of the current doesn't really matter. The distance will always remain constant.
D = speed * time
D = 0.45 * 160
D = 72m
D = speed * time
D = 0.45 * 160
D = 72m
