The beep test is a fitness activity used in sports. Participants run back and forth between markers spaced $20 m$ apart, in time to a series of beeps. The beeps get faster over time, and when a participant can no longer keep up, they have to drop out.

A Physics student is correctly measuring the displacement of a participant during a section of the beep test.
