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?
11:30 AM
11:50 AM
12:10 PM
12:20 PM
In 2 hours, the clock will gain 10 minutes (5 minutes/hour * 2 hours). So, when the clock shows 12:00 PM, the actual time will be 12:00 PM - 10 minutes = 11:50 AM.

Q
Q: 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?
Solution: In 2 hours, the clock will gain 10 minutes (5 minutes/hour * 2 hours). So, when the clock shows 12:00 PM, the actual time will be 12:00 PM - 10 minutes = 11:50 AM.
Steps: 6
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.
