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 3500.0 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.

Rate = 84mL/s

A minute has 60 seconds;

Rate = 84mL/s * 60s = 5040 mL/minute

Volume of blood in a minute = Rate * Number of beeats per minute

Volume = 5040 * 72 = 362880 mL

How long to circulate 3500ml?

1 minute = 362880mL

x = 3500 mL

x = 3500mL min / 362880mL

Math Expression:

Time to circulate 3500ml of blood (min) = 3500ml * 1 minute / Volume of blood at a rate of 84ml/s and 72 beats per minute (ml)
