The hydraulic conductivity of a 30-m-thick confined aquifer was determined by laboratory testing to be 4.7 x 104 m/s. If the straight-line portion of a Jacob semilogarithmic plot goes through the points (t = 10³ day, s = 0.3 m) and (t = 102 day, s = 0.6 m) for an observation well 30 m from a pumping well, calculate the transmissivity and storativity of the aquifer.

Kindly give me right solution with step by step. 

The hydraulic conductivity of a 30-m-thick confined aquifer was determined by laboratory testing
to be 4.7 x 104 m/s. If the straight-line portion of a Jacob semilogarithmic plot goes through the
points (t = 10³ day, s = 0.3 m) and (t = 102 day, s = 0.6 m) for an observation well 30 m from a
pumping well, calculate the transmissivity and storativity of the aquifer.
