Question

If a normal human heart pumps 5200 mL of blood in one minute, how much blood will it pump in 15 seconds. (Hint: 15 seconds is equal to 1 quarter of a minute)

Answer 1

Blood pumped in 1 minute= 5200 mL

Blood pumped in a quarter of a minute= <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{1}{4}$ of 5200 mL
= 5200 mL <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> ÷ 4
= 1300 mL
