The clock shows 3:45, but it's 15 minutes slow. So we need to add 15 minutes to the clock time to get the actual time. 3:45 + 0:15 = 4:00 The actual time is 4:00. However, the text also says that the actual time is "a quarter past an hour," meaning it is 15 minutes past the hour. Since we already determined the actual time is 4:00, we need to add 15 minutes to get to the next quarter hour mark: 4:00 + 0:15 = 4:15 Therefore, the correct time based on the given information is 04:15 in HH:MM format.
