Average velocity = total displacement ÷ total time
Determine the initial position and final position
Calculate displacement = final position − initial position
Measure the total time taken
Divide displacement by total time
Include direction with the result
Use units such as m/s or km/h
For motion in one dimension, keep the sign of displacement
For motion in two or three dimensions, use vector displacement
If the object returns to its starting point, average velocity is zero
