Hey thanks for the help: I have another question:
A swimmer is capable of swimming 0.30 m/s in still water.
(a) If she aims her body directly across a 75 mwide river whose current is 0.55 m/s, how far downstream (from a point opposite her starting point) will she land?
(b) How long will it take her to reach the other side?

timetogetacross=75m/.30m/s
Now use that time to figure how far downstream with the water velocity. 
I'm not sure I quite understand what you mean

^ That was me btw
