To find the average number of heartbeats per second, we need to divide the total number of heartbeats by the total time in seconds.
First, we can calculate the total number of heartbeats. The graph shows a line representing resting heart rate, which is a horizontal line at a constant value. Since the y-axis represents heartbeats, the constant value of the line represents the resting heart rate in beats per minute (bpm).
To calculate the total number of heartbeats, we need to multiply the resting heart rate (in bpm) by the total time in minutes. The total time in minutes can be calculated by dividing the total time in seconds by 60 (since there are 60 seconds in a minute).
Let's assume the resting heart rate is given as 60 bpm and the total time in seconds is 60 seconds.
Total time in minutes = 60 seconds / 60 = 1 minute
Total number of heartbeats = Resting heart rate (in bpm) x Total time in minutes
= 60 bpm x 1 minute
= 60 heartbeats
Now, we need to convert the total number of heartbeats into heartbeats per second by dividing it by the total time in seconds.
Average number of heartbeats per second = Total number of heartbeats / Total time in seconds
= 60 heartbeats / 60 seconds
= 1 heartbeat per second
So, the average number of heartbeats per second is 1.
