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.
