Question

The school of a boy is 1 km towards North to his home. A road connecting his home and the school is straight. Find the distance and displacement of the boy from the home.

Answer 1

The distance of school from boy's home is 1 km, therefore the distance covered by the boy when he reaches school is,
$s=1km$
and the displacement of the boy is,
$disp=1km$

But, if the boy return back to the home from the school then the distance covered by the boy is,
$s=2km$
And as the boy reaches back to its original position therefore the displacement made by him is,
$disp=0km$
