My old toaster can hold at most two slices of bread and toast them on one side at a time.  I want my bread toasted on both sides and buttered on one side. It takes 3 seconds to put each slice into the toaster, 30 sec to toast one side of 1 or 2 slices, 3 sec to reverse a slice, and 12 sec to butter one (that side must already be toasted). Assume only one of these operations can be done at a time. In how short a time can I toast & butter three slices?

The greatest challenge to any thinker is stating the problem in a way that will allow a solution.
