How long does it take an automobile traveling in the left lane of a highway at 60.0 km/h to overtake (become even with) another car that is traveling in the right lane at 20.0 km/h when the cars' front bumpers are initially 75 m apart?

    I just answered this duplicate posting

    So the relative velocity is 40km/hr.
    The relative distance is 75m

    distance=velocity*time

    .075km=40km/hr * time

    time=.075/40 hrs. I get a little over six seconds.
