Expert Answer
time taken =?
Amount of water = 3l = 3000 mL
percolation rate = 25 mL/min
percolation rate = amount of water (mL) / time taken for percolation
Thus, the time taken for percolation = amount of water (mL)/ percolation rate
Time taken = 3000 mL/ 25 mL/min = 120 minutes
So, time-taken by the water to percolate in the given sample of soil is 120 minutes.
