To find the average number of heartbeats per second, we need to consider that a typical resting heart rate is usually between 60 to 100 beats per minute. To convert this to beats per second, we divide by 60.
For example:
- 60 beats per minute / 60 seconds = 1 beat per second
- 100 beats per minute / 60 seconds ≈ 1.67 beats per second
Given the options provided, 2 beats per second seems to fit within the typical range for a resting heart rate, likely representing a simplified average.
Therefore, the most reasonable response from the options is 2 beats per second.
