Answer 1

The statement that must be true about the two postal delivery workers is:

They each have a displacement of 0 miles.

Displacement is defined as the change in position from the starting point to the ending point. Since both workers start and end at the post office, their displacement is zero, regardless of the distance they traveled during their routes.

The other statements are not necessarily true: they may travel different distances, and they likely have different velocities depending on their routes and speeds.
