Question

Anthony walks to the pizza place for lunch. He walks 1 km east, then 1 km south and the 1 km east again. What distance did he cover? What was his displacement?

Answer 1

Distance$=1+1+1=3km$

Displacement$=\sqrt{1^2+2^2}=\sqrt{5}$

Distance is the total movement of an object without any regard to direction. We can define distance as how much ground an object has covered despite its starting or ending point.
