9) y=.028(9.2)^2-1.1(9.2+.1)+68
y= 60.14/9.2
avg. change=6.54
y=.028(9.2)^2-1.1(9.2+.01)+68
y=60.24/9.2
avg. change=6.547
y=.028(9.2)^2-1.1(9.2+.001)+68
y=60.25/9.2
avg. change+6.55
@ t=9.2 sec its rate will be 6.55

Please resubmit this and include a statement of the problem.
A couple of suggestions:
It looks like you are dividing the value of y by the value of t. In general this is not an important result, though in certain applications it can be.
However it does not give an average rate of change. The average rate of change of y with respect to t is change in y / change in t. A single value of y, or a single value of t, does not constitute a change in that quantity.
Also be sure to include enough significant figures in your y values to guarantee that the difference, and hence the rates you obtain, have a sufficient number of significant figures to allow comparisons with other rates.
