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.
