How long does it take an automobile traveling 66.8 km/ h to become even with a car that is traveling in another lane at 50.8 km/ h if the cars" front bumpers are initially 144 m apart? Answwe in units of s.

  • physics -

    The distance to travel is 144m
    The difference in speed is 16km/hr

    144m / 16km/hr * 1km/1000m = 9/1000 hr * 3600s/hr = 32.4s
