    Ellie: s = 4 m/h

    Justin: s = 1.5m/h

    D = r • t

    D is distance apart

    r is rate/speed

    t is time

    r = 4 + 1.5 = 5.5 mph

    d = 22m

    Find t?

    22 = 4•t

    22/4 = t

    t = 5.5 h

    It will take 5.5 hours to meet up.

    It would take 55 hours until Ellie and Justin meet. This is found in the equation y=55h aka y=55x.

    Answer: y=55h
