Fiona drives 18 meters east and 24 meters south. What is the magnitude of her displacement?

15 m

18 m

20.0 m

30.0 m

35 m

30.0 m

Explanation:

Displacement is the distance between her initial position and her final position.

In this case, it's the hypotenuse of the right triangle formed by the east and south distances.

x² = (18) ² + (24) ²

x = 30.0
