The minute hand of a 12 hour analog clock is situated precisely on a minute mark, while the hour hand is situated exactly 2 minute marks behind the minute hand.

What time is it?

Note: For purposes of the problem, each hour mark is deemed as a valid minute mark.

Well, just rambling here. Each minute mark is 7.5 degrees. So there will be 15 degrees between the two hands. And in conclusion, it will be 4:24
 
For the record, how did you do it?
 
i don't get it, why 4.24 could it not be other numbers?
