2006 Cayley Problem 23

Quincy and Celine have to move 16 small boxes and 10 large boxes. The chart indicates the time that each person takes to move each type of box. They start moving the boxes at 9:00 a.m. The earliest time at which they can be finished moving all of the boxes is

\begin{array}{|l|c|c|}\hline & \text{Celine} & \text{Quincy} \\ \hline \text{small box} & \text{2\ \text{min}.} & \text{3\ \text{min}.} \\ \hline \text{large box} & \text{6\ \text{min}.} & \text{5\ \text{min}.} \\ \hline\end{array}

\textbf{(A)}\ 9:41 \text{ a.m.}\quad \textbf{(B)}\ 9:42 \text{ a.m.}\quad \textbf{(C)}\ 9:43 \text{ a.m.}\quad \textbf{(D)}\ 9:44 \text{ a.m.}\quad \textbf{(E)}\ 9:45 \text{ a.m.}
