Gone fishing. Debbie traveled by boat 5 miles upstream to
fish in her favorite spot. Because of the 4-mph current, it
took her 20 minutes longer to get there than to return. How
fast will her boat go in still water

  • algebra - ,

    Distance = D = 5 miles
    Still water speed = S
    current speed = 4 m.p.h.
    Time to go upstream,T1 = 5/(S-4)
    Time to go downstream, T2 = 5/(S+4)
    Difference,
    T1-T2 = 20/60 hour
    Can you take it from here?
