velocity = displacement / time
as displacement can be 0, average velocity can be 0
speed = distance / time
as distance cannot be 0 average speed cannot be 0
Eg: in uniform circular motion, after completion of one round distance displacement becomes 0 so average velocity is 0. However, since some distance is covered, there is average speed.
