What is the purpose of a reference point?

Some life forms move so slowly that their movement cannot be detected by normal observation. The best way to determine any movement is by placing a mark at some point, and observing any change in position from it. Why is this true?
Zamir and Talia raced through a maze. Zamir walked 2 m north, 2 m east, 4 m south, 2 m east, 4 m north, 2 m east, 3 m south, 4 m east, and 4 m north. Talia walked 2 m north, 6 m east, 3 m south, 4 m east, and 4 m north.

How are all paths that have a displacement of zero similar?
All paths with a displacement of zero share the characteristic that the starting position and the ending position are the same. Regardless of the distance traveled or the complexity of the path taken, if the object returns to its original point of origin, the net change in position (displacement) is zero.

Recall the previous question and the scenario with Zamir and Talia finding their way through a maze.Why is their displacement the same when the distance each traveled was different?
Distance is the total path length traveled by each person, so if they took different routes, their distances will differ. Displacement is the straightline change in position from the starting point to the ending point. Since Zamir and Talia started at the same entrance and ended at the same exit, their displacement is identical regardless of the paths they took.
