the human heart pumps 750 gallons of blood in 9 hours. A human kidney filters 100 gallons of blood in 6 hours. How many more gallons of blood does the human heart pump than a human kidney filters during a 24 hour period?

Given :
Amount of blood human heart pumps in 9 hours = 750 gallons
Amount of blood pumped in 1 hour = 750/9
= 83.33 gallons
So, blood pumped in 24 hours = 24 * 83.33
= 2000 gallons (approx.)
Blood filtered by kidney in 6 hours = 100 gallons
so, Blood filtered by kidney in 1 hour = 100/6
= 16.66 gallons
Blood filtered by kidney in 24 hours = 16.66 * 24
= 400 gallons (approx.)
So, the difference in blood pumped by heart and blood filtered by kidney = (2000 - 400) gallons
= 1600 gallons
Thus, human heart pump 1600 gallons more blood than a kidney filters in 24 hours .
