Click here to see the graph from my book.

i understand the midpoint rule is

\(\displaystyle \frac{b - a}{n}\)

so \(\displaystyle \frac{12}{4} = 3\)

so \(\displaystyle n = 3\)

I also know that

\(\displaystyle \frac{1}{12} \int^{12}_{0} v(t)dt \)

But now I'm stuck... any guidance anyone can offer would be great.
