A river is flowing with a constant speed of 2.00 km/h. A swimmer starts at a dock, swims upstream to another dock that is 550 m away, and then swims downstream back to the dock at which she started. If the swimmer can manage to swim a constant 5.00 km/h relative to the water, how long does her round trip take?
