Question

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

Answer 1

Answer:

200 m North

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.
