## Toasting Bread

Your toaster is broken, so you decide to toast your bread in a pan. The pan can hold three slices of bread at a time and takes 1 minute to toast one of their sides. How much time would it take you to toast four slices of bread on both sides using the pan?

**SOLUTION**

It would take you 2 minutes and 40 seconds. Label the slices with A, B, C, D, their top sides A1, B1, C1, D1, and their bottom sides A2, B2, C2, D2.

- Toast A1, B1, C1 for 40 seconds.
- Toast A2, B2, D1 for 40 seconds.
- Toast A1, C2, D2 for 20 seconds.
- Toast A2, C2, D2 for 20 seconds.
