A truck enters a highway driving 60mph. A car enter the highway at the same place 14 minutes later and drives 66mph in the dame direction. From the time the car enters the highway, how long will it take the car to pass th truck?

  • MATH -

    d1 = d2,

    14min = 14/60 = 0.2333h.

    60t = 66(t - 0.2333),
    60t = 66t - 15.4
    60t - 66t = -15.4,
    -6t = -15.4,
    t = 2.57h.

    t - 0.2333 = 2.57 - 0.2333 = 2.33h to
    catch up.
