For this case we can find the unit rate in number of minutes per page.
To do this, we divide the total time between the number of pages.
We have then:
[tex]r = \frac {20} {5} \frac {min} {pag}\\r = 4 \frac {min} {pag}[/tex]
Answer:
The unit rate olive is reading is:
[tex]r = 4 \frac {min} {pag}[/tex]
