Answer 1

The correct 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 difference between the initial and final positions of an object. Since both workers start and end their routes at the post office, their initial and final positions are the same, resulting in a displacement of 0 miles. The other statements do not have to be true for both workers.
