Solve the following using Python:

Initially, a prescription drug $(200$ mg$)$ is in the blood $(5$ liters$).$ The drug leaves the blood by entering a tissue region $(8$ liters$)$ where the drug is metabolized $($disappears$)$ at a first order rate with k $=0\mathrm{.}01$ min$-1.$There is no reaction of the drug in the blood. The transport coefficient of the drug $($kC$,$drug$)$ for the blood$/$tissue interface is $0\mathrm{.}80$ cm$/$min $($i$.$e$.$ it absorbs rapidly$)$ and the transport area is $100$ cm$2.$ The drug can transport between both regions $($not just one way$).$ You may assume the tissue and blood regions are well$-$mixed $($i$.$e$.$ drug diffuses rapidly within each region$)$ and that each region is constant volume.

How long does it take for $90\%$ of the drug to disappear from the blood?

Answer: $338$ min
