Dave is painting a fence in his uncle's yard. He painted 2 sections of the fence in 30 minutes. Dave has 9 more sections to paint.

Question

If Dave paints at the same rate, how many minutes will it take him to finish?

Answer 1

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.
