Ms. Perry travels north 5 km, 10 Km west, and then turns and travels 5 Km south. What is her displacement?

Her displacement is 10km

Explanation:

An illustrative diagram for the journey is shown in the attachment below.

From the question,

She travels north 5km, which is given by /AB/ in the diagram, and 10km west, which is given by /BC/ in the diagram. She then travels 5km south, which is given by /CD/ in the diagram. To determine her displacement,

Displacement is the shortest distance from an initial position to a final position.

Therefore, her displacement is given by /DA/ in the diagram.

NOTE: /DA/ = /BC/ (Opposite sides of a rectangle)

Since /BC/ = 10km

∴ /DA/ = 10km

Hence, her displacement is 10km.

Isuck at math i am no sorry
