"Quarter past three" means the time displayed in the mirror is .
To find the actual time from a mirror image of a clock, subtract the mirror time from (which represents ):
\begin{array}{r@{\quad}l} 11 & 60 \\ -\quad 3 & 15 \\ \hline 8 & 45 \end{array}
Therefore, the actual time shown by the clock is .
