## Homework Statement

H------S-----C

Sandra is represented by S, Home is represented by H, and C is represented by commercial mall.

If Sandra walks home, what is her displacement if the commercial mall is the origin?

The distance between H and S is 2 miles and the distance between S and C is represented by D.

D = 3.0 miles.

## Homework Equations

Displacement = xf - xo/t

## The Attempt at a Solution

I'm not sure if I have the concept of displacement down right...it should be the right overall change in position from its start to final, but when I do this problem it doesn't make sense.

So C is the origin (xo) so its value is 5 and H is 0. So the overall displacement should be -5, but when I did the problem, it said -5 was incorrect. So I'm not sure what I did wrong.
