To determine the average number of heartbeats per second, I'd need to refer to the details provided in the image you mentioned. However, since I can't view images, I'll provide guidance on how to calculate heartbeats per second based on common knowledge.
Typically, a human heart beats around 60 to 100 times per minute. To convert that into beats per second, you can divide by 60. For instance:
- If the heart beats 60 times per minute, then it would be 1 beat per second (60/60).
- If the heart beats 100 times per minute, then it would be about 1.67 beats per second (100/60).
Therefore, you would typically find that the average number of heartbeats per second for a resting adult is between 1 to 2 beats.
If you are looking for a specific answer from the options provided, please consider the context or information explicitly stated in your source. Based on general knowledge, "2 beats per second" could be a reasonable average for this context if an active heart rate is considered.
If you can provide additional context or figures from the image, I would be able to give you a more precise answer!
