To find the average number of heartbeats per second from the graph described, you need to determine the total number of heartbeats over the total time.
From the information given:
- The x-axis represents time in seconds, ranging from 0 to 12 seconds.
- The y-axis represents heartbeats, ranging from 0 to 18.
Assuming the resting heart rate remains constant throughout the 12 seconds, you would identify the heart rate value on the graph.
Let's say the line indicating the resting heart rate on the graph shows a heart rate of 6 beats at 12 seconds.
To find the average beats per second:
- Total heartbeats = Heart rate * Time = 6 beats * 12 seconds = 72 beats.
- Average beats per second = Total heartbeats / Total time = 72 beats / 12 seconds = 6 beats per second.
However, without the specific heart rate value from the graph, we can't calculate the exact average.
If the resting heart rate was lower, say at 3 beats per second, the calculation becomes:
- Total heartbeats = 3 beats/second * 12 seconds = 36 beats.
- Average beats per second = 36 beats / 12 seconds = 3 beats per second.
From your response options, if we worked with 3 beats per second, that would fit one of the choices.
Please identify the heart rate directly shown on the graph to finalize which option to select for the average number of heartbeats per second. If the heart rate remains at 3 beats per second, then the correct response is:
3 beats per second.
