at what exact time after 12 o´clock does the minute-hand cross over the hour-hand?

Question

please...your time should be in format of an hour, minute and secound. I realize it is after 1:05 but i need exact time

Answer 1

If the smallest division is seconds, then there are 60*60=3600 of these in an hour. Assuming the hands move every second, then the hour hand moves 1/3600 of 1/12 around the clock in one second.

Starting from midnight, with the hour hand and the minute hand tied, let n=the number of hours, x=the number of seconds after midnight. Then x/(12*3600) is the part it has moved in x seconds, and x/3600-n is the part the minute hand will be at.

If the two hands are tied,

x/(12*3600)=x/3600-n

n=11x/(12*3600)

We know the next tie must occur on the first circuit, so n=1 and

x=3600*12/11.

So it happens at 1 and 1/11 hour.

Hi. First you need to know if the clock has a continuous motion or if it "ticks and tocks". The difference is that the minute hand moves in little jerky motions once per tick/tock. If this resulted in one movement per second, say, you simply need to know which second has the minute hand PAST the hour hand, which is 01:05:06. If it is a continuous motion clock the answer is a bit complicated because of your term "cross over". You really want to know when they line up, I think, but it's your question! Hope this helps.

Answer 3

Answer 6

properly, i will't write with my left hand in any respect! yet I do countless issues with my left hand, apparently i'm left hand eye co-ordinated. Or properly, whichever is the different of what properly handers ought to be! I open doors, carry bags and do maximum stuff with my left hand.

Answer 7

I'm pretty sure it's 1:05:30. might be wrong.
