d = [(s – 4) ⁄ (s² – 9s + 20)] • [(s – 5) ⁄ 4]    ...    rearrange terms 
d = (s – 4) • (s – 5)   ⁄   [4(s² – 9s + 20)]    ...    factor denominator 
d = (s – 4) • (s – 5)   ⁄   [4(s – 4) • (s – 5)] 
d = ¼ mile

f(t) =  -16t^{2} +48t + 100
Average rate of change from t = 3 seconds to t = 5 seconds = \frac{f(5)-f(3)}{5-3} =  \frac{(-16( 5^{2})+48(5)+100)-(-16( 3^{2})+48(3)+100  }{2}=\frac{(-16(25)+240+100)-(-16(9)+144+100)}{2} = \frac{(-400+240+100)-(-144+144+100)}{2}= \frac{-60-100}{2} = \frac{-160}{2} = -80
