Answer: The clock skipped 3 seconds on average per 30 minutes.
Step-by-step explanation:
• The starting time, when the clock was accurate = 12 noon on Friday
• The final time, when the clock was late by 468 seconds = 6 pm on Monday
• The number of hours between final time and initial time = 3 days and 6 hours = (3 x 24) + 6 = 78 hours
• Therefore, the number of 30 minutes duration in 51 hours
= 78 x 2 = 156
• Total late time = 468 seconds
Hence, the average of seconds the clock skipped every 30 minutes
= Total late time/ Number of 30 minutes duration
= 468 / 156
= 3 seconds
The correct answer is 3 seconds
