    Inverse variation means y=k/x (direct variation is y=kx) so we can use the info given to find the constant k

    y=k/x

    6=k/900

    k=6 (900)

    k=5400 so the equation is:

    y=5400/x or more accurately for this problem

    t (v) = 5400/v then:

    t (800) = 5400/800

    t (800) = 6.75 hours
