    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
