Answer :
To find out what time it was three hours ago from 3:00, you simply subtract three hours from the current time.
Starting at 3:00, if you go back one hour, it would be 2:00.
Going back two hours, it would be 1:00.
Finally, going back three hours, it becomes 12:00.
So, three hours ago, the time was 12:00.
This problem involves basic subtraction of time, which is a common skill used to manage schedules and understand the passage of time. It's important to understand how to add or subtract hours to determine different times of the day.
