9. A student performs an experiment to measure a soil's percolation rate. Through the soil sample, she allowed 500 mL of water to percolate. She noticed it took about 20 minutes for the water to pass. What is the rate of water percolation in the soil?
(a) 0.04 mL/min
(b) 25 mL/min (c) 100 mL/min
(d) 10000 mL/min

Answer:
Given,
Amount of water = 200 mL
Percolation time = 40min
Rate of percolation = Amount of water in mL / Percolation time in min
=200 / 40
=5 mL/min.
Hence, the rate of percolation of water through the given soil sample is 5 mL/min.
