    Answer:

    Distance = 80 meters

    Explanation:

    Given the following data;

    Speed = 72 km/hr

    Time = 4 seconds

    Conversion:

    72 km/hr to meters per seconds = 72*1000/3600 = 72000/3600 = 20 m/s

    To find the distance covered by the car;

    Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

    Mathematically, speed is given by the formula;

    Speed = \frac{distance}{time}

    Making distance the subject of formula, we have;

     Distance = speed * time

    Substituting into the above formula, we have;

     Distance = 20 * 4

    Distance = 80 meters
