Question

The average adult heart pumps about 84. mL/s of blood at 72 beats per minute. Suppose you need to calculate how long it would take the average heart to circulate 5300. mL of blood. Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols.

Answer 1

Explanation:

The given data is as follows.

            Rate of heart pump = 84 ml/sec

            Beats per minute = 72

            Flow or volume = 5300 ml

It is known that relation between time, flow and rate is as follows.

               Time = $\frac{Flow}{Rate}$

Therefore, putting the given values into the above formula as follows.

                   Time = $\frac{Flow}{Rate}$

                            = $\frac{5300 ml}{84 ml/sec}$

                            = 63.09 sec

Thus, we can conclude that 63.09 sec would be taken by the average heart to circulate 5300 mL of blood.
