Answer:
[tex]\dfrac{7}{72}\ \text{mL/minute}[/tex]
Step-by-step explanation:
The tank loses [tex]2\dfrac{1}{3}[/tex] milliters every 24 minutes
[tex]2\dfrac{1}{3}\ \text{mL}=24\ \text{minutes}\\\Rightarrow 1\ \text{minute}=\dfrac{2\dfrac{1}{3}}{24}\ \text{mL}\\\Rightarrow 1\ \text{minute}=\dfrac{\dfrac{7}{3}}{24}\ \text{mL}\\\Rightarrow 1\ \text{minute}=\dfrac{7}{3}\times\dfrac{1}{24}\\\Rightarrow 1\ \text{minute}=\dfrac{7}{72}\ \text{mL}[/tex]
The rate at which the amount of water changes per minute is [tex]\dfrac{7}{72}\ \text{mL/minute}[/tex]
