Answer 1

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ h(t_2)}}-{{ h(t_1)}}}{{{ t_2}}-{{ t_1}}}\impliedby \begin{array}{llll} average\ rate\\ of\ change \end{array} \\\\\\ h(t)=300-16t^2\quad \begin{cases} t_1=0\\ t_2=3 \end{cases}\implies \cfrac{h(3)-h(0)}{3-0}\implies \cfrac{h(3)-h(0)}{3}$
