1) The rate of percolation would be 0.33 ml/s
Percolation rate = volume of water/time
= 600/1800s
= 0.33 ml/s
2) The percentage of water absorbed would be 40%
Percentage of water absorbed = amount absorbed/total water x 100
amount of water absorbed = 100 - 60
= 40 ml
total amount of water = 100 ml
Percentage of water absorbed = 40/100 x 100
= 40%
