The clock shows 3:45. It's 15 minutes slow, so the actual time is 3:45 + 15 minutes = 4:00. However, the text also states, "The actual time is a quarter past an hour." This means the actual time's minutes must be :15. The calculation (4:00) contradicts the explicit description (XX:15). This indicates a logical flaw or a trick in the riddle. If we assume: 1. The most direct correction for the clock (3:45 + 15 min) gives us the actual *hour* part. (3:45 -> 4:00, so the hour is 4). 2. The explicit statement "The actual time is a quarter past an hour" gives us the actual *minutes* part. (:15). Combining these, the time would be 4:15. Let's check for consistency: If the actual time is 4:15, it is indeed "a quarter past an hour". If the actual time is 4:15, and the clock is 15 minutes slow, the clock should read 4:15 - 0:15 = 4:00. However, the text says "The clock shows 3:45." This 4:00 != 3:45. The problem contains a logical inconsistency. However, if forced to provide a single HH:MM time by prioritizing the explicit statement about the actual time's format and the most immediate derived hour: The hour is derived from 3:45 + 15 minutes = 4:00. So the hour is 4. The minutes are explicitly stated as "a quarter past an hour" = 15. 4:15
