Thank you for your help and everyone makes sense but what I don't understand is why for some equations the average velocity and instantaneous velocity are equal and some aren't. In this case the average velocity for both equations is calculated for t=4 seconds centered at t=2. But for the...

If x(b)= 20-15b+2b^2 then why would average and instantaneous velocity values be the same? If x(b)= 20-15b+2b^3 then why would average and instantaneous velocity values be different? What would the magnitude of the difference mean? I think in x(b)= 20-15b+2b^2 average and instantaneous...
