Answer: 4 hours

Step-by-step explanation:

Given : A construction company is building a fence that is $\dfrac{2}{3}$ mile long.

i.e. Length of fence = $\dfrac{2}{3}$ mile .

They can build $\dfrac{1}{6}$ mile of fence every hour.

i..e Time taken to build $\dfrac{1}{6}$ mile fence= 1 hour

Then, Time taken to build 1 mile fence= $\dfrac{1}{\dfrac{1}{6}}=6\text{ hour}$ [By Unitary method]

Then , Time taken to build $\dfrac{2}{3}$ mile fence = $\dfrac{2}{3}\times6\text{ hour}$

=4 hours.

Hence, it will take 4 hours to complete the fence.
