Answer

To determine the average number of times a healthy human breathes in a minute, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Breathing**: Breathing consists of two main processes: inspiration (breathing in) and expiration (breathing out). Together, these processes make up one complete breath.

2. **Identifying the Average Rate**: The average breathing rate for a healthy adult at rest is typically measured in breaths per minute.

3. **Considering the Options**: We have several options to choose from:
- Option 1: 20 to 40
- Option 2: 1 to 6
- Option 3: 12 to 16
- Option 4: 16 to 25

4. **Analyzing the Breathing Rate**: It is known that the normal breathing rate for a healthy adult is around 12 to 16 breaths per minute. This is considered a resting rate and can vary based on factors such as age, fitness level, and activity.

5. **Selecting the Correct Answer**: Based on the information provided and the analysis of the options, the correct answer is:
- **12 to 16 breaths per minute** (Option 3).

### Final Answer:
On average, a healthy human breathes **12 to 16 times per minute**.
