To find out how long it will take Dave to paint the remaining 9 sections of the fence, we first need to determine his painting rate.
Dave painted 2 sections in 30 minutes. Thus, his rate of painting is:
\[
\text{Rate} = \frac{2 \text{ sections}}{30 \text{ minutes}} = \frac{1 \text{ section}}{15 \text{ minutes}}.
\]
Now, to find out how long it will take him to paint 9 sections, we multiply the number of sections by the time it takes to paint one section:
\[
\text{Time for 9 sections} = 9 \text{ sections} \times 15 \text{ minutes/section} = 135 \text{ minutes}.
\]
Therefore, it will take Dave **135 minutes** to finish painting the remaining sections.
