What is the formula of pancake problem?

The formula for the pancake problem is:

Number of pancakes = (number of pancakes ×2)/ How many pancakes do you eat at a time?

Note: When there is a remainder, the number of pancakes is+1.

Total time = OEM times × OEM time on each side.

Example:

The class asked the canteen master to bake a cake for 26 students, 26 parents and/kloc-0 teachers in their class. If the pot can bake three cakes at a time, both sides of the cakes should be baked for 2 minutes, how many minutes should the canteen master bake at least?

Analysis: The canteen master baked a cake for 26 students, 26 parents and 1 teacher in the class. Then * * * needs to bake 26+26+ 1=53 cakes.

According to the formula, the number of pancakes = (number of pancakes ×2)/ how many pancakes to eat at a time = (53 * 2)/3 = 35... 1, so it needs to be baked 35+ 1=36 times. Bake for 2 minutes each time, * * * 2×36 = 72 minutes.

The copy agency needs to print 9 sheets of materials, and both sides need to be printed. If you can print at most two at a time, how many times do you need to print at least?

Analysis: This question is the deformation of the pancake problem, and the printed materials are essentially the same as pancakes.

Number of pancakes = (number of pancakes ×2)/ How many pancakes to eat at a time =(9*2)/2=9 times.
