The average adult human heart pumps of blood(the number of beats is irrelevant, as we are given the volume of blood the human heart pumps per second and not per beat)
We need to find out how many seconds it would take for the human heart to pump out 7200mL of blood, which is expressed by the formula
The amount of blood to be pumped is 7200mL, and the blood pumped per seconds is 84mL
Hence, the time to pump is {s stands for seconds}
