- 3 seconds to put each slice into the toaster and,
- 30 seconds to toast one side of 1 or 2 slices and,
- 3 seconds to reverse a slice and,
- 12 seconds to butter one side (that side must already be toasted).
- 3 seconds to remove a slice from the toaster without putting it back in reverse.
In how short a time can Ricardo toast and butter three slices?
