This problem has been posted before and made sense but when I was trying to solve on my own, I wasn't getting the same answers as what was given. Please explain the steps taken as I have noticed there are a few equations to use for these solutions.

Problem statement A tank holding several contaminants (including chloride at 10,000 mg/L and dissolved TCE at 5mg/L ) leaks rapidly over an area of 10m2 into a thin aquifer with a groundwater velocity of 0.25m/ day. Use Dx=1.0m2/ day and Dy=0.1m2/ day. Bulk density for the aquifer is 1.8kg/L and porosity is 0.25 . The KD for TCE on aquifer materials was measured to be 0.5L/kg. A groundwater well for a farm is located 75m away. a. Calculate the time [days] required for the chloride plume center of mass to reach 75m. 2b. Calculate the time [days] required for the TCE plume center of mass to reach 75m. 2c. Calculate the Maximum concentration of chloride in the plume [mg/L] at the farmer's well
