total distance = 90+90 = 180 m
total time = 1 min = 60 sec
displacement = 90-90=0
average speed = total distance/ total time = 180/60 = 3m /sec
average velocity = displacement/ time = 0/60 = 0 m/s

average speed =total distance /total time taken
so , average speed = 180/given time
average velocity =displacement /time
so, average velocity = 0/given time
( 0 displacement because initial and finall position concide

aishwarya931: thank you
