    Explanation:

    Given that,

    A shopper walks Eastward 3.2 meters and then westward 7.2 meters.

    Let East is positive direction and west is negative direction.

    Initially, he walks +3.2 m and finally, he walks (-7.2 m)

    Distance = 3.2 m + 7.2 m = 10.4 m

    Displacement = final position – initial position

    = -7.2-3.2

    =-10.4 m

    The negative sign shows west direction. It means that direction of shopper is due west.
