They each travel a distance of 0 miles. They each have a displacement of 0 miles. They each have a displacement of 0 miles. They travel the same distance.

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 postal delivery workers start at the post office and return to the post office, their displacement is 0 miles, regardless of the distance they traveled while delivering mail along their routes.

The other statements are not necessarily true; they may not have the same velocity or travel the same distance.
