**16:00** The clock shows 3:45 but is 15 minutes slow, so actual time is 4:00. 4:00 is “a quarter past” 3:45 only if considering relative phrasing loosely — but here “quarter past an hour” means HH:15 unless “an hour” refers to the previous hour. Wait — rereading: Clock shows 3:45, but 15 minutes slow → actual time = 4:00. They also say: “The actual time is a quarter past an hour.” Quarter past an hour means HH:15, not HH:00. This is contradictory unless “an hour” means the hour that just passed — but usually quarter past 4 means 4:15, not 4:00. So maybe they mean: Actual time = HH:15. Given clock slow by 15 min → if actual is 15 minutes past the hour and clock is 15 minutes behind, clock should show HH:00. We know clock shows 3:45, so HH:00 = 3:45? That would mean HH = 3? Then actual time = 3:15? But that doesn’t fit: If actual = 3:15 and clock is 15 min slow → clock should show 3:00. Alternatively: Clock shows 3:45 slow by 15 → actual 4:00. But then “actual time is a quarter past an hour” does not match unless “an hour” means 3:00 (so quarter past 3:00 = 3:15 — not matching 4:00). Contradiction. Only consistent if “quarter past an hour” refers to **quarter past the upcoming hour** (nonsense) or they meant “quarter to an hour” → but says quarter past. But if we stick to the facts given: slow by 15 min → actual = 4:00. Maybe “quarter past an hour” is irrelevant mistakenly included. Answer based on first logic: Time = **16:00** (This matches 15 minutes after 3:45.) **Final answer**: 16:00
