A clock gains 6 minutes every hour. If it was set correctly 9 hours ago, how far from the correct time is it now?

Correct answer: Option C — 54 minutes fast. Total gain = rate × elapsed time = 6 × 9 = 54 minutes. Option A (54 minutes slow) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option B (48 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option D (60 minutes fast) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.
