Assuming that the distance from the heart to the brain is 30 centimeters, and the motion of blood in the aorta is 30 centimeters per second. There fore to solve for the time needed for the blood to reach the brain is:
t = 30 centimeters / 30 cm per second
t = 1 second.
The regular heart rate is 70 beats per minute, solve for the equivalent number of beats:
number of beats = 70 beats / minute * (1 min / 60 seconds) * 1 second
number of beats = 1.2 beats
Therefore, it takes 1.2 beats for the heart to pump blood to the brain.
