Answer:
c) 2 blocks
Step-by-step explanation:
Her displacement is the difference between her starting point and her ending point.
Let's say she starts at the origin, (0, 0).
First, she goes 13 blocks east: (13, 0)
Next, she goes 4 blocks north: (13, 4)
Then she goes 8 blocks west: (5, 4)
Then she goes 6 blocks south: (5, -2)
Finally, she goes 5 blocks west: (0, -2)
The magnitude of her displacement is the distance between her initial and final positions: 2 blocks.
