Plan one: bake one piece at a time

Each cake needs to be baked on two sides, each side takes 3 minutes.

Then it takes: 6×3=18 minutes to bake three cakes with this method.

Option 2: bake two cakes first, then bake the third cake

Follow the rules in the question and you can bake up to two cakes at a time.

The first three minutes are used to bake the front side of the first and second pages;

The second three minutes are used to bake the back sides of the first page and the second chapter;

Use 3 minutes each on the front and back of the third cake.

The total time required for this plan is: 6×2=12 minutes

Option 3: First bake the front of two sheets, then bake the back of one and the third. The fronts of the three sheets were stamped, and the remaining two were soldered on the backs.

In the first 3 minutes, iron the first and second front sides;

In the second 3 minutes, iron the first reverse side and the third front side;

< p>The third 3 minutes is used to burn the reverse side of the second sheet and the reverse side of the third sheet.

The time used for this plan is: 3×3=9 minutes

Of course, the third plan is better, it takes less time, and you can eat the cake faster. Fry two cakes in the pan at a time. Don't let the pan sit idle (if there is any spare time). This saves the most time.
