Answer:
Displacement
Step-by-step explanation:
We are given that average velocity is different than average speed.
We have to find what involves average velocity.
Average velocity:It is defined as the displacement per unit time.
Mathematical representation,
Average velocity=

Average speed:It is defined as the distance per unit time.
Average speed=

Average velocity is different from average speed because calculating average velocity involves displacement but average speed involves distance.
