An object is moving on a straight line. The position $($in inches$)$ of the object is measured relatively to the starting point and it can be defined using the position function $s(t)=t^3-4t+3$

Which of the following is the formula that can be used to find the average velocity on the interval $3,5?$

What is the average velocity on the interval $3,5?$

$V_{av}=\frac{s(5)-s(3)}{5-3},V_{av}=45i\frac{n}{sec}$

None of these

$V_{av}=\frac{s(3)-s(5)}{5-3},V_{av}=-45i\frac{n}{sec}$

$V_{av}=\frac{s(5)-s(3)}{5-3},V_{av}=99i\frac{n}{sec}$
