Answer:
Total: 200 meters, Displacement: 100 meters South
Explanation:
First, add up the meters traveled to get the total distance.
50m + 150m = 200m
Lastly, displacement is the shortest distance from the initial position to the final position. The person first walked 50 meters north but then traveled 150 meters south. Therefore, their displacement was 100 meters south.
50m - 150m = -100m
(Note: Directions are vectors. North and East are positive vectors while South and West are negative)
