A swimmer maintains a speed of 0.15 m/s relative to the water when swimming directly toward the opposite shore of a straight river with a current that flows at 0.75 m/s.
(a) How far downstream is the swimmer carried in 1.5 minutes?
(b) What is the velocity of the swimmer relative to an observer on shore?
I'm not sure, sorry.
The Attempt at a Solution
I know this involves relative velocity and maybe vectors, but I am unsure. Please help.
Thank you very much.
