because the student finally arrive the point from where he started his journey......

Answer 2

Given:

A student who walks 3 blocks east, 2 blocks north, 3 blocks west, and then 2 blocks south

To Find:

The total displacement
Solution:

The displacement is defined as the shortest distance between two points. Also, if the starting point and the ending point are the same then the displacement is 0.

In the given question a student first walks 3 blocks east then he walks 2 blocks North then 3 blocks West and at last 2 blocks South. We can see that the student is at last at the same point from where he started. So the starting point and the ending point are the same, so he covered zero displacement.

Hence, the total displacement of the student is 0.
