Question

Andrea walked 1 block north and then 2 blocks west. how would you determine her total displacement?

Answer 1

draw a vector from where she started to where she finished

Step-by-step explanation:

it might be worded differently on apex but I just answered this question

Answer 2

1 block North and 2 blocks west are going to be legs of the triangle.
Total displacement is hypotenuse.
So, we can use Pithagorean Formula.

D² = 1² + 2² =5 m²

D =√5 m
