QuestionSetting up the math for a one-step quantitative problem $0 / 5$ Yatziri
The average adult heart pumps about $84 . \mathrm{mL} / \mathrm{s}$ of blood at 72 beats per minute. Suppose you need to calculate how long it would take the average heart to circulate $3500 . \mathrm{mL}$ 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. $\text { time }=$ $\square$
$\mu$ $\square$

Studdy Solution

STEP 1

1. The average adult heart pumps $84 \, \text{mL/s}$ of blood.
2. We need to calculate the time it takes to circulate $3500 \, \text{mL}$ of blood.
3. We are looking for an expression that represents the time in seconds.

STEP 2

1. Define the known quantities.
2. Set up the mathematical expression.

STEP 3

Identify the known quantities: - Blood flow rate: $84 \, \text{mL/s}$ - Total blood volume to circulate: $3500 \, \text{mL}$

STEP 4

Set up the mathematical expression for time:
The time $t$ it takes to circulate $3500 \, \text{mL}$ of blood can be calculated using the formula:
$\text{time} = \frac{\text{Total blood volume}}{\text{Blood flow rate}}$
Substitute the known values:
$\text{time} = \frac{3500 \, \text{mL}}{84 \, \text{mL/s}}$
The mathematical expression for the time it takes to circulate $3500 \, \text{mL}$ of blood is:
$\boxed{\frac{3500 \, \text{mL}}{84 \, \text{mL/s}}}$
