To find the average number of heartbeats per second, we need to find the sum of the number of beats for each second and divide it by the total number of seconds.
The graph shows that at second 0, there are 6 beats per second.
At second 1, there are 8 beats per second, an increase of 2 beats.
At second 2, there are 15 beats per second, an increase of 7 beats.
At second 3, there are 18 beats per second, an increase of 3 beats.
To find the total number of beats, we add up the number of beats at each second:
6 + 8 + 15 + 18 = 47 beats
To find the average number of beats per second, we divide the total number of beats by the total number of seconds:
47 beats / 4 seconds = 11.75 beats per second
So, the average number of heartbeats per second is 11.75 beats per second.
