Serjik [45]

B

We can perceive this question as a vector (which has both magnitude and direction). The magnitude is the displacement and the direction is where they are headed.

Explanation:

The displacement (magnitude of the vector) for Callie, which is also equal to the distance, is; 4m + 3m = 7m while that of Sue is 5m. Therefore the displacement for Callie is greater than Sue’s.

Nonetheless the direction in the vector is the same, which is towards point C.
