To determine how long it will take Dave to finish painting the remaining sections of the fence, we first find his painting rate.
Dave painted 2 sections in 30 minutes, so his rate is:
\[
\text{Rate} = \frac{2 \text{ sections}}{30 \text{ minutes}} = \frac{1 \text{ section}}{15 \text{ minutes}}
\]
Now, Dave has 9 more sections to paint. To find out how long it will take him to paint these 9 sections, we can calculate:
\[
\text{Time for 9 sections} = 9 \text{ sections} \times 15 \text{ minutes/section} = 135 \text{ minutes}
\]
Thus, it will take Dave **135 minutes** to finish painting the remaining sections.
