A girl walks 30 m east. She then walks 30 m west, back to where she started.
Which statement about her whole walk is correct?
The distance is 0 m0\ \text{m}0 m and the displacement is 60 m60\ \text{m}60 m
The distance is 60 m60\ \text{m}60 m and the displacement is 60 m60\ \text{m}60 m
The distance is 0 m0\ \text{m}0 m and the displacement is 0 m0\ \text{m}0 m
The distance is 60 m60\ \text{m}60 m and the displacement is 0 m0\ \text{m}0 m
