Question 3
Alan has an old grandfather clock that runs slow. Every day at 9:00 AM it shows 8:30 AM, so he resets it. One day Alan went on a “4-day vacation”. He left at 9:00 AM on Monday after resetting the clock. When he returned at 9:00 PM on Thursday, what time did the clock show?
Assume the clock loses time at a constant rate. Use the exact departure and return times, rather than treating “4-day vacation” as four complete 24-hour days. Enter H:MM AM/PM or 24-hour HH:MM, without a day name.
Automatic short-text checking is limited to listed spellings/formats, not general meaning. An unsupported/null result means ungraded and needs manual checking; it is not evidence that an answer is wrong.
