Razia conducted an experiment in the field related to the rate of percolation. She observed that it took 40 min for 200mL of water to percolate through the soil sample. Calculate the rate of percolation.
Time = 40 min ;
Volume of water = 200mL Amount of water
So, Rate of percolation (mL/min)= 
= 
Therefore, percolation rate of water = 5mL/min
