## Question:

The function s(t) represents the position of an object at time t moving along a line. Suppose s(2) = 136 and s(3) = 156. Find the average velocity of the object over the interval of time {eq}\left [ 1, 4 \right ] {/eq}.

## Average Value of a Function

One of the methods to compute the average value of a function is through definite integrals. The average value of a function {eq}f(x) {/eq} defined on the interval {eq}[a,b] {/eq} is given by {eq}\displaystyle \bar{f} = \frac{1}{b-a} \int_a^b f(x) \text{ d}x {/eq}.
