Displacement

Hi joshua,

Displacement of an object is the overall change in distance from its starting location.
Therefore, since the object is traveling 20km south, then 11km south again,
the total distance south would be 20+11
= 21km south

Same with the 9km west and 3km west.
The total distance west would be 9+3
=12km west

Therefore, the displacement of the object would be 21km south, 12 km west. It is in whole numbers.

I don't know what the answer would be in degrees, but this site might help:
