If 'twice as long since noon' as it was two hours ago, what time is it now?

Explanation:
This question tests how to compare elapsed time from a fixed reference point. If the current time after noon is x hours, then two hours ago the time since noon would be x − 2. The statement means the present elapsed time is twice as long as the elapsed time two hours ago, so x = 2(x − 2). Solving gives x = 4. So it is four hours after noon, which is 4:00 pm.
