Question

Aaliyah walks 45 meters East, 45 meters South, and 45 meters North. What is her resultant displacement?

i think 45 meter's east

Answer 1

yes

Answer 2

"displacement" = vector from start to finish
magnitude = 45 , direction = east
In your car you need both odometer and compass

"distance" is just a scalar, you just need the odometer and it would be 45+45+45
