Answer 1

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

They each have a displacement of 0 miles.

Displacement refers to 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 indeed 0, regardless of the distance they may have traveled along their routes. The other statements are not necessarily true.
