1. In still water, a student can swim at 1.2 m/s. She swims perpendicularly across a 40 m wide river, landing 30 m downstream. In crossing the river, what distance does the student move? 2. d=df-di, cosine, sine, tangent 3. Again, i tried drawing out a picture. I made 40m the x axis, and 30m the y axis. Am i trying to solve for the hypoteneuse? Also, what am i suppossed to do with the 1.2m/s. is it just there to try and mess me up? or is it important for the question?
