Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Rate of percolation = Volume of water ÷ Time taken = 200 ml ÷ 30 min = 6.67 ml/min (approximately). Option C (6.66 ml/min) is the closest and most accurate answer, using the exact calculation 200 ÷ 30 = 6.666... ml/min. Option A (7) is too high, B (10) is incorrect, and D (6) is too low.
