    Automobile must travel at 96 mph to pass the truck in 4 seconds.

    Step-by-step explanation:

    Length of automobile = 16 feet = 4.88 m

    Length of truck = 28 feet = 8.53 m

    Speed of truck = 30 mph = 48 km/h = 13.33 m/s

    Time in which automobile to pass truck = 4 s

    Distance traveled by truck in 4 seconds = 4 x 13.33 = 53.33 m

    Distance which need to cover by automobile in 4 seconds to pass truck is the sum of length of automobile, length of truck and distance traveled by truck in 4 seconds.

    Distance which need to cover by automobile in 4 seconds = 4.88 + 8.53 + 53.33

    Distance which need to cover by automobile in 4 seconds = 66.74 m

    Distance = Speed x Time

    66.74 = Speed x 4

    Speed = 16.69 m/s = 60 km/h = 96 mph

    Automobile must travel at 96 mph to pass the truck in 4 seconds.
