Riddle:
Susan uses a toaster that has 2 slots. The toaster toasts one side of each piece of bread at a time, and it takes exactly 1 minute to do so.
If Susan wants to make three pieces of toast, what is the LEAST amount of time she needs to toast them on both sides?
Show Answer
Answer:
3 minutes.
She puts two
pieces in the toaster, toasting one side of each. Then she flips one of them, takes one out, and puts the completely untoasted
piece into the toaster. Finally, she takes out the toasted
piece and puts the two half-toasted
pieces of bread into the toaster for a minute and she's done.
