You Are Attempting to Calculate the Discharge of Groundwater in the Marshak

You are attempting to calculate the discharge of groundwater in the Marshak Aquifer.The measured height of the water table in Well A is 300 and is 175 m in Well B,and the wells are 15,000 m apart.The Marshak Aquifer is composed of fine-grained sandstone with a hydraulic conductivity of 3×10 ^-⁵ m/s,and a cross-sectional area of 2 m².What is the discharge of the Marshak Aquifer?

A) 0.5× 10 ^-7 m/s
B) 6.0× 10 ⁵ m/s
C) 5.0× 10 ⁵ m/s
D) 5.0× 10 ^-7 m/s
