Vectors- River Race. who won the race?

a boy and a girl decide to have the "annual" who's the best contest. Both are capable of swimming at 4.000m/s. they decide to race from the south shore to a point directly north, on the opposite shore, 200.0m distant, across a river that is flowing 3.00m/s towards the east. the boy swims directly northward, and is pushed downstream, meaning that he has to run back to the finish line, at a speed of 7.500m/s. the girl heads into the current such that she ends up at the finish line. who won the race? By what margin?
