Question

Answer 2

Understanding the Problem

The problem states that an alarm clock was set correctly at 12:00 and started running, but it was 1 minute behind the actual time. When the clock showed 13:00, it was wound up, but after that, it started running 1 minute fast. The question is asking for the actual time when the clock will show 14:00.

Solution

To solve this problem, we need to determine the time it takes for the clock to advance by 1 hour (from 13:00 to 14:00) and then subtract that time from the clock's current time (13:00) to find the actual time.

Let's break down the problem step by step:

1. The clock was set correctly at 12:00 but started running 1 minute behind the actual time. Therefore, when the clock showed 13:00, the actual time was 13:01. 2. The clock was wound up at 13:01, but it started running 1 minute fast. This means that for every 60 minutes on the clock, only 59 minutes pass in actual time. 3. We need to find the time it takes for the clock to advance by 1 hour (from 13:00 to 14:00) in actual time. Since the clock runs 1 minute fast for every 60 minutes, it will take 60 minutes in actual time for the clock to advance by 59 minutes. 4. Therefore, the actual time when the clock will show 14:00 is 13:59.

Answer: The actual time when the clock will show 14:00 is 13:59.
