#### Answer

$79.5$ it is greater than $65$

#### Work Step by Step

Suppose $s(t)$ is the distance covered by the trucker at time $t$.
Thus, $s(0)=0$ and $s(2)=159$
Need to use The Mean Value Theorem to calculate the velocity at time $t$.
This states that $|v(t)|=|s'(t)|=|\dfrac{f(b)-f(a)}{(b-a)}|$
or, $|\dfrac{s(2)-s(0)}{(2-0)}|=\dfrac{159}{2}=79.5$ it is greater than $65$
