As 
graph is a parabola, it can be given as 
, where 
and 
are constants. Since it is symmetrical 
s, we have equal displacements at 
and 
that tells us that line 
joining two coordinates is parallel to the 
-axis. Hence, slope of 
is zero. This implies that the average velocity during the time interval 
s is zero
