Can you answer this question correctly?
The time is 3:15
What is the angle between the hour hand and the minute hand?

7.5 degrees?

NA if it's digital, hysteresis if it's analog.

'The answer to this is not zero! The hour hand, remember, moves as well. The hour hand moves a quarter of the way between three and four, so it moves a quarter of a twelfth (1/48) of 360 degrees. So the answer is seven and a half degrees, to be exact.'

awwww, at least wait 'til someone gets it wrong.

You're on a programming forum, how many people are you really expecting to get this wrong? Many of our professional lives revolve around the science of problem solving and logical thinking.

Implementation defined.

Winner.

I'm with Zacs7 on this - the amount and step of the movement of the hour hand in relation to the second hand is defined only in an "ideal" clock/watch, but actual implementations may use arbitrary "steppiness". Most likely, the hour hand moves once every minute, but it may move once every two minutes, once every 30 seconds or once every second - or any other amount.

If we are talking ideal clock, then 7.5 degrees (0.25 * 360/12) would be correct.

For example, the 10-hour clock http://www.antique-horology.org/_Edi...Images/181.jpg

And yes this clock was used. I'm sure there are countless other analog clocks. Perhaps your question gave not enough information :)

I'm lost :S an analog clock like 00:00 doesn't move at all, so it has to be zero :O

Do you mean a DIGITAL clock?

I considered this, naturally. However, if I've learned anything from my professional experience, I've learned that it's better to give the answer they expect to hear and let it be rather than give the right answer and try to explain why. :)

lol, metric clocks
