Dame Washalot is preparing breakfast for Kiki and her friends Sati & Ariel. Each kid wants Washalot to toast 1 slice of bread for him. The toaster however holds only 2 slices of bread and toasts only 1 side at a time. Therefore, Washalot toasts one side of a slice of bread, takes out the slice, turn it overs, and puts it back in the toaster to toast the other side. It is known that it takes exactly 1 minute to toast 1 side of a slice of bread. Washalot is however smart enough to have figured out a way to toast 3 slices on both sides in only 3 minutes. How does she do it?
