For this problem, we are given the distance a construction crew built a road and the time in days it took to build it. We need to determine the unit rate for this problem, which is achieved by dividing the distance and time. We have:
[tex]\text{ unit rate}=\frac{\frac{1}{2}}{\frac{1}{6}}=\frac{1}{2}\cdot\frac{6}{1}=\frac{6}{2}=3\text{ miles per day}[/tex]The unit rate is 3 miles per day.
