You walk 20 meters north, then 5 meters south. what is your displacement?
a: 15 meters
b: 25 meters
c: 15 meters north
d: 25 meters north

The answer is C. 15 meters North

Displacement is the distance and direction from the origin. If you move 20 meters North, your displacement is 20 meters North. If you move 5 meters South, you are basically moving back the way you came by 5 meters, which means you are now 15 meters North.

I hope this helped! :)
