Question

What is the displacement if you walk 100m north, then 200m south, then 300m north ​

Answer 1

200 m North

Step-by-step explanation:

1. Let's represent north as positive and south as negative.

(100 m)+(-200 m)+(300 m)

= 200 m

2. Since the answer is positive, the units are 100 m NORTH since north represents positive.
