Calculating the Minimum Time to Fry 15 Potato Pancakes

To find the minimum amount of time needed to fry 15 potato pancakes on both sides, we can use the information given about the time it takes to fry each pancake on one side.

Given: - Each pancake takes 1 minute to fry on one side. - The skillet can hold 2 pancakes at a time.

Solution:

To minimize the time needed to fry 15 potato pancakes on both sides, we can use the following approach:

1. Fry 2 Pancakes at a Time: - Since the skillet can hold 2 pancakes at a time, we'll fry 2 pancakes together to optimize the use of time.

2. Fry on One Side, Then Flip: - Fry the first side of the pancakes, then flip them to fry the second side.

3. Total Time Calculation: - We'll calculate the total time needed to fry 15 pancakes using the approach described above.

Calculation:

1. Fry 2 Pancakes at a Time: - It takes 1 minute to fry 2 pancakes on one side.

2. Fry on One Side, Then Flip: - After frying one side for 1 minute, we'll flip the pancakes and fry the other side for an additional 1 minute.

3. Total Time Calculation: - Since we can fry 2 pancakes at a time, we'll need to repeat this process 8 times to fry 16 pancakes (8 times 2 pancakes = 16 pancakes). - Therefore, the total time needed will be 8 minutes (8 times 1 minute = 8 minutes).

Conclusion:

The minimum amount of time needed to fry 15 potato pancakes on both sides is 8 minutes.
