The difference between average speed and average velocity is as follows —

Average Speed	Average Velocity
The ratio of the total distance travelled by the body to the total time of journey is called its average speed.	If the velocity of a body moving in a particular direction changes with time, the ratio of displacement to the time taken in the entire journey is called its average velocity.
Avg Speed = $\dfrac{\text{Total Distance}}{\text{Total time}}$	Avg Velocity = $\dfrac{\text{Displacement}}{\text{Total time}}$
Average speed can never be zero.	It can be zero, even if average speed is a non-zero value.
