No Time to Waste

Strategies and Hints

The minimum time is 3 minutes and 25 seconds. Do all computations in seconds. The best procedure is:

 Put in slice 1 ----- 5 seconds Put in slice 2 ----- 5 seconds

Slice 1 now has 5 seconds; slice 2 has 0 seconds.

 Fry for 55 seconds ----- 55 seconds

Slice 1 now has 60 seconds; slice 2 has 55 seconds.

 Remove slice 1 ----- 5 seconds Put in slice 3 ----- 5 seconds

Slice 1 now has 60 seconds; slice 2 has 65 seconds; slice 3 has 0 seconds.

 Fry for 55 seconds ----- 55 seconds

Slice 1 now has 60 seconds; slice 2 has 120 seconds (the two minutes to finish); slice 3 has 55 seconds.

 Remove slice 2 ----- 5 seconds Put in slice 1 ----- 5 seconds

Slice 1 now has 60 seconds; slice 2 is done; slice 3 has 65 seconds.

 Fry 55 seconds ----- 55 seconds

Slice 1 now has 115 seconds; slice 2 is done; slice 3 has 120 seconds (the two minute to finish).

 Remove slice 3 ----- 5 seconds

At this point, all three pieces of toast are done!

 Remove slice 1 ----- 5 seconds

Total time is 205 seconds or 3 minutes and 25 seconds.
