Answer 2

Answer: d = 0

Explanation: Displacement is defined as the change of position of an object.

So if the initial position is the porch, then walks a mile, and then returns (this means that the final position is also the porch)

So the initial position and the final position is the same, this means that the total displacement, d, is equal to zero.
