    Time = (distance) / (speed)

    Time = (0.25 km) / (65 km/hr)

    Time = 0.00385 hour

    (That’s 13.85 seconds.)

    Better way:

    Distance = 0.25 km

    Distance = 250 meters

    Speed = (65 km/hr) x (1000 m/km) x (1 hr/3600 sec)

    Speed = 18.06 m/sec

    Time = (250 m) / (18.06 m/s)

    Time = 13.85 seconds
