Final answer:
The ant's displacement can be found by using the Pythagorean theorem to calculate the magnitude of the total displacement. The ant walked 12m to the right and 11m down, so its displacement is approximately 16.28m.
Step-by-step explanation:
The ant's displacement can be found by using the Pythagorean theorem to calculate the magnitude of the total displacement. The ant walked 12m to the right and 11m down, so its displacement is the hypotenuse of a right triangle with sides of 12m and 11m.
Using the Pythagorean theorem, we get:
Displacement = sqrt((12m)^2 + (11m)^2)
Displacement = sqrt(144m^2 + 121m^2)
Displacement = sqrt(265m^2)
Displacement = 16.28m
The correct answer is not provided in the options, but the ant's displacement is approximately 16.28m.
