What is the average number of heartbeats per second?
A. 2/3 per second
B. 3 beats per second
C. 1 1/2 per second
D. 2 beats per second
The average number of heartbeats per second is D. 2 beats per second
To find the average number of heartbeats per second, we need to convert the given options into a common unit.
A. 2/3 per second = 0.67 beats per second
B. 3 beats per second
C. 1 1/2 per second = 1.5 beats per second
D. 2 beats per second
Therefore, the average number of heartbeats per second is the same as option D, which is 2 beats per second.
To find the average number of heartbeats per second, we need to divide the total number of heartbeats by the time in seconds.
Let's analyze the options given:
A. 2/3 per second: This means that there are 2/3 or approximately 0.67 heartbeats per second.
B. 3 beats per second: This option suggests that there are 3 heartbeats per second.
C. 1 1/2 per second: This option implies there are 1 1/2 or 1.5 heartbeats per second.
D. 2 beats per second: This option suggests there are 2 heartbeats per second.
To determine the correct option, we need to know the average number of heartbeats per second for humans. According to scientific research, the average resting heart rate for adults is between 60-100 beats per minute.
To convert beats per minute to beats per second, we divide the number of beats by 60 since there are 60 seconds in a minute.
Calculating the range for average heartbeats per second:
Minimum: 60 beats per minute / 60 seconds = 1 beat per second
Maximum: 100 beats per minute / 60 seconds = 1.67 beats per second
Comparing the given options to the range, we can determine that option C, 1 1/2 per second, falls within the correct range for the average number of heartbeats per second.
