04:15 Here's the explanation: 1. The clock shows 3:45, but it's 15 minutes slow. 2. To find the correct time, add 15 minutes to the displayed time (3:45 + 0:15 = 4:00). 3. The actual time is a quarter past an hour, which means it's 15 minutes after the hour. 4. Since we already adjusted the time to 4:00, adding another 15 minutes gives us the final correct time: 4:15. Therefore, the correct time is 04:15.
