Answer 1

Explanation:

Distance is the path travelled by an object.

Displacement is the shortest path between source and destination. DISTANCE is scalar quantity and

Displacement is vector quantity.

Here DISTANCE between school and boy's House is 1km.

He goes to school from home and comes back to home. So TOTAL DISTANCE he travelled is :

=1km +1km =2km

But the displacement travelled by body is zero = 1km - 1km=0 km

As the source and destination is same.
