Note : Be careful with speed and velocity, even the formula is same that 
1. If we would like to find the velocity, we must calculate the distance from initial to final,
,
2. If we would like to find the speed, we must calculate the total distance that travelled (
.
So, in this question, because it return back to its initial point so (delta)x = 0, so average velocity is 0 m/s.
