    Answer:

    Upstream 18mph              Downstream  36 mph

    Step-by-step explanation:

    Upstream DATA:

    distance = 180 miles ; time = 10 hrs ; rate = 180/10= 18 mph

    —–

    Downstream DATA:

    distance = 180 miles ; time = 5 hrs ; rate = 180/5= 36 mph

    ——

    Equation:

    Upstream: b – c = 18 mph

    Downstream: b + c = 36 mph

    Now solve for “b”

    solve for “c”
