A swimmer is heading straight for the other shore of a river with a velocity of vs=0.7 m/s relative to the water, but is carried away by the current, which has a velocity of vr=0.3 m/s. It takes her 20.3 s to get across. How far downstream does she end up?

Can someone please help me? I don't know where to start.
