ANSWER


1.28\text{ weeks}

Step-by-step explanation

The rate at which they built the road is 3 km per week and they built 3.84 km of the road.

To find the time it took to make the road, divide the distance made by the rate:


\begin{gathered} rate=\frac{\text{distance}}{\text{time}} \\ \text{time}=\frac{\text{distance}}{\text{rate}} \end{gathered}

Therefore, the time taken (in weeks) is:


\begin{gathered} \text{time}=(3.84)/(3) \\ \text{time}=1.28\text{ weeks} \end{gathered}

That is the answer.
