Question

Given:• 1 cm^3= 1 mL• 1 dm^3 = 1 L• 1L = 1,000 mLIf a health person's kidneys can filter 125 mL of blood per minute, then how long will it take for the kidneys to filter 4.5 L of blood?

Answer 1

`\begin{gathered} \frac{125mL}{\text{ minute}} \\ 4.5L \\ t=\text{?} \\ \frac{125mL}{\text{ minute}}\cdot(1L)/(1,000mL)=0.125\frac{L}{\text{minute}} \\ \\ t=\frac{4.5L}{0.125(\frac{L}{\text{minute}})}=36\text{minutes} \\ \text{The kidneys will take 36 minutes to filter 4.5L of blood} \end{gathered}`
