A well fully penetrates a \(30\) m thick confined aquifer. After a long period of pumping at a constant rate of \(0.06\) m\(^3\)/s, drawdowns of \(3.6\) m and \(2.0\) m are found at distances \(60\) m and \(120\) m away from the well, respectively. The hydraulic conductivity of the aquifer is \(n \times 10^{-4}\) m/s. The value of \(n\) is ________ (Rounded off to two decimal places)
