HEY!!!!!!
____&____
Average speed is the ratio of total distance by TOTAL time taken. As average velocity depends on displacement and displacement can be zero if the object returns to initial position . ... Whereas displacement is zero as source and destination is same.
Hence A body can have zero average velocity but not zero average speed....
