A watch loses 4 minutes every 24 hours. It is set correctly at noon on Monday. What time does it show when the true time is 6 pm on Thursday?
Answer and explanation
Correct answer: A. 5:47 pm
- Step 1: From noon Monday to 6 pm Thursday is 3 days 6 hours = 3.25 days. Step 2. The watch loses 3.25 × 4 = 13 minutes. Step 3. 6:00 pm - 13 minutes = 5:47 pm. Answer: 5:47 pm. Why not the others: 5:48 pm: This counts only 3 days of lost time, 12 minutes. 6:13 pm: This adds 13 minutes instead of taking them away. 5:44 pm: This counts 4 full days of lost time, 16 minutes.
