Diver questionim so confused

    Diver question..im so confused :(

    1. The problem statement, all variables and given/known data

    A swimmer is capable of swimming 0.35 m/s in still water.
    (a) If she aims her body directly across a 75 m-wide river whose current is 0.40 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?

    2. Relevant equations

    I think I could use D= do+Vit+1/2at^2
    and a^2+b^2=c^2
    3. The attempt at a solution



    ahh.. im so confusedddd

    Hint: Horizontal and vertical velocities are independent of each other.

    Finding the answer to (b) first might prove easier.
