\begin{gathered} \text{Total time=36}(3)/(4)=(147)/(4)\min ute \\ on\text{ dressed}\Rightarrow(147)/(4)*(1)/(4)=(147)/(16)\min ute \\ \text{eating}\Rightarrow20\text{ minute} \\ \text{bed}\Rightarrow\text{4 minute} \\ \text{drive time=}(147)/(4)-((147)/(16)+20+4) \\ \Rightarrow3.56\text{ minute} \end{gathered}
