A confined aquifer of 15 m constant thickness is sandwiched between two aquicludes as shown in the figure (not drawn to scale) Piezometer P 55.2 m Piezometric Surface Aquiclude Aquifier: Piezometer Q Aquiclude 34.1 m L = 2500m The heads indicated by two piezometers P and Q are 55.2 m and 34.1 m, respectively. The aquifer has a hydraulic conductivity of 80 m/day and its effective porosity is 0.25. If the distance between the piezometers is 2500 m, the time taken by the water to travel through the aquifer from piezometer location P to 0 (in days. round off to 1 decimal place) is
