Show answer & explanation
Correct answer: C
Answer: 11:38 PM
Reasoning:
The watch gains 8 seconds every 4 minutes, so per minute it gains 2 seconds. That is 2 seconds × 60 = 120 seconds = 2 minutes per hour.
Time from 4:00 AM to 11:00 PM is 19 hours.
Total gain = 19 hours × 2 minutes/hour = 38 minutes.
Therefore, at the actual time 11:00 PM the fast watch will read 11:38 PM.
Note: If expressing the total gain in seconds, 19 × 120 = 2280 seconds, and 2280 ÷ 60 = 38 minutes.
