A clock gains 5 minutes every hour. If it shows 10:00 AM now, what will be the actual time when it shows 12:00 PM?
Correct Answer: 11:50 AM
Step 1: Understand that the clock gains 5 minutes for every hour.
Step 2: Calculate the total time from 10:00 AM to 12:00 PM. This is 2 hours.
Step 3: Calculate how many minutes the clock gains in those 2 hours. It gains 5 minutes each hour, so in 2 hours it gains 5 minutes/hour * 2 hours = 10 minutes.
Step 4: When the clock shows 12:00 PM, it has gained 10 minutes.
Step 5: To find the actual time, subtract the gained time from the clock time: 12:00 PM - 10 minutes = 11:50 AM.
Step 6: Therefore, the actual time when the clock shows 12:00 PM is 11:50 AM.
