Converting 4.5 fm to m,


\begin{gathered} 4.5\text{ fm}*(\frac{10^(-15)\text{ m}}{1\text{ fm}})=4.5*10^(-15)\text{ m} \\ \end{gathered}

Converting m to nm;


(4.5*10^(-15)\text{ m})*(\frac{10^9\text{ nm}}{1\text{ m}})=4.5*10^(-6)\text{ nm}

Therefore, 4.5 fm equals to 4.5×10^(-6) nm.

Converting 450 miles/hr to feet/s;


\begin{gathered} 450\text{ miles/hr}=450\text{ miles/hr}*(\frac{5280\text{ feet}}{1\text{ mile}})*(\frac{1\text{ hr}}{60\text{ min}})*(\frac{1\text{ min}}{60\text{ sec}}) \\ =660\text{ feet/sec} \end{gathered}

Therefore, 450 miles/hr equals to 660 feet/sec.
