Ron and Tiffany Are Studying Circulatory System Function -Ron and Tiffany Modified the Experiment to See How Long

question 8

Multiple Choice

Ron and Tiffany are studying circulatory system function. They designed an experiment to test whether the diameter of a tube affects the rate of flow through the tube. In their experiment, they ran water from a large container through five tubes with different diameters for exactly 30 seconds for each tube. They measured the volume of liquid that passed through the tube during the 30-second period, testing each tube three times and pouring the water back into the container after each test. The results of the experiment are shown in the following table.
$\begin{array} { | l | l | l | } \hline& \text { Diameter of } &{ \text { Average Volume } } \\ & \text { Tube } ( \mathrm { cm } ) & \text { Fluid (mL) } \\\hline \text { Tube A } & 0.5 & 210 \\\hline \text { Tube B } & 0.6 & 350 \\\hline \text { Tube C } & 0.7 & 480 \\\hline \text { Tube D } & 0.8 & 600 \\\hline \text { Tube E } & 0.9 & 975 \\\hline\end{array}$
-Ron and Tiffany modified the experiment to see how long it would take to pass 1,000 mL of fluid through each tube. Based on the results shown in the table, which tube would it take the longest for 1,000 mL of fluid to flow through?

• A) tube A
• B) tube B
• C) tube C
• D) tube D
• E) tube E
