Answer:
Negative
Step-by-step explanation:
According to Cartesian Coordinate System all directions towards left and downwards are taken to be negative and Upwards and right are considered positive.
If you consider east as going right and west as going left then the you will represent distance towards west as negative integer.
Since the she walked 8 km which is more than the initial 5 km, she has walked farther than the point P towards left hence you will represent her final position by negative
