A casserole is removed from a $375^{\circ} \mathrm{F}$ oven, and it cools
to $200^{\circ} \mathrm{F}$ after 15 minutes in a $75^{\circ} \mathrm{F}$ room. How long
(from the time it is taken out of the oven) does it take
to cool to $100^{\circ} \mathrm{F} ?$ (Hint: Use Newton's Law of Cooling,
$\left.T(t)=T_{m}+\left(T_{0}-T_{m}\right) e^{-k t} .\right)$
