What Time Is It?

Here’s a math puzzle that is rather easy. Or is it?

You look in a mirror and see the reflection of a clock. In the reflection, the clock appears to show a time of 11:51. What is the real time?

Before I share the solution, how ’bout some clock jokes?

A hungry clock goes back four seconds.

I spent 35 minutes fixing a broken clock yesterday.
At least, I think it was 35 minutes…

What’s the difference between a man and a broken clock?
At least a broken clock is right twice a day.

It took me four hours to eat a dozen clocks.
It was very time consuming.

An alarm clock made of herbs will help you wake up on thyme.

My clock stopped at 8:23 a.m. I’m going to have a day of morning.


Puzzle Solution

The puzzle above is based on a math trivia question I found at Trivia Cafe.

The answer could be 12:09, if the reflection in the mirror looks like this…

11:51 Analog Clock

Then again, the answer could be 12:11, if the reflection in the mirror looks like this…

11:51 Digital Clock

And of course, there are all the silly possibilities — for instance, if the clock is broken, it doesn’t matter what time shows in the reflection, regardless if it’s analog or digital.
