Answer: D.
position: −15 m; displacement: −10 m
Explanation:
Displacement is the distance travelled in a specific direction.
Given that an ant starts at −5 m and moves 10 m left, 25 m right, 30 m left, and 5 m right
Total displacement = -10 + 25 – 30 + 5
Total displacement = -10
And the position = -10 -5 = -15
The correct answer is therefore D.
position: −15 m; displacement: −10 m
