Final answer:
The woman's final position is -15 m.
Step-by-step explanation:
In this question, the woman starts at -10 m and has three successive displacements of -5 m. To find her final position, we need to add up the displacements. The total displacement is -5 m + (-5 m) + (-5 m) = -15 m.
So the woman's final position is -15 m.
