Lucas read

[tex]\begin{gathered} \frac{208}{8}=26\text{ pages/hour} \\ \frac{156}{6}=26\text{ pages/hour} \\ \frac{234}{9}=26\text{ pages/hour} \end{gathered}[/tex]

Therefore, Lucas presents a constant read rate.

Brianna read

[tex]\begin{gathered} \frac{168}{6}=28\text{ pages/hour} \\ \frac{120}{4}=\text{ 30 pages/hour} \\ \frac{348}{12}=29\text{ pages/hour} \end{gathered}[/tex]

Therefore, Brianna does not present a constant read rate.

Which of the tables, if any, shows a proportional relationship?

Lucas's table presents a constant read rate - 26 pages/hour.
