It took 25 minutes for the soil from Sarah's backyard to percolate 250 mL of water through it. The percolation rate of the soil is:
Open in App
Solution
The correct option is A 10 mL/min
Percolation rate is the speed at which the water moves through the soil.
Total amount of water passed = 250 mL
Total time taken = 25 minutes
Percolation rate = Amount of water passed/ Time taken
∴ Percolation rate = 250 mL/25 min
= 10 mL/min
Percolation rate is the speed at which the water moves through the soil.
Total amount of water passed = 250 mL
Total time taken = 25 minutes
Percolation rate = Amount of water passed/ Time taken
∴ Percolation rate = 250 mL/25 min
= 10 mL/min
