Ok!!
As for the second question, why is the limit always zero?
The average acceleration is $\displaystyle \frac{20}{\frac{1}{6}} = 120 \,\textrm{mi}/\textrm{h}^2 $
Since the function is continuous and
OK, so it's graph is a decreasing function, right? Or can we say something more specifically?

Re: Limits & properties
Let's take a look at a couple of examples.
Klaas van Aarsen Today, 05:31If $f(x)=x$, then $f'(x)=1$ and $f''(x)=0$.
So $\lim\limits_{x\to +\infty}f'(x)\ne 0$,
