Can anyone tell me the formula I would use to solve this question.

If 2001.51 = 70% of X, what is X?

I know what X is, (2859.30) but if I didn't, and only had the 2001.51 number, what is the formula I would use to determine X?

And what area of math is this referred to as, (since I obviously need a course on it ;-) Thanks.

That's a 6th grade math problem.

Thank you for pointing that out, Abraham. What would we do without you?

Are any of you seriously mathematical? If so I have a question that should be simple, but none of my local geniuses can answer it.

Shoot it here.

Goody! How do you calculate the points at which the hour and minute hands of a clock are in the same exact position (or exactly opposite) other than 12:00?

Mind you, the exact times are of secondary interest at best. I mainly want to know how they'd be arrived at, simply because I'm an endlessly curious person (if a total mathematical failure).

I'm sure that you could work this to the nanosecond. How close do you want it?

From Noon, the next time that the two hands are equally placed are 65 and a fraction of a minute later, again, pending to what significant figures you want it calculated to.

Since this is simply a curiosity thing primarily if not exclusively, that extra five minutes that the minute hand has to move every hour to get past exactly 65 minutes later, is approximately 25 seconds. 5/60 of the next 5 minutes.

So every 65 minutes and 25 seconds the two hands will be equal.

Simple linear math entails that they're opposite exactly half-way prior to or after (however you'd like to view it since it's identical) the next (prior to) or last (after), which means that every 65 minutes and 25 seconds, exactly halfway out of phase with when they're equally aligned, they are opposite.

This also entails that this occurs 32 minutes and 43 seconds after and before the next identical alignment.

Another way of looking at it is that in one 12 hour period they align, or are opposite, 11 times, either one.

12 hours = 720 minutes.

720 minutes/11 = 65.45

.45 minutes = .45 x 60 = 27 seconds. That extra 2 seconds or so, is from the additional time of movement that the hour hand moves in the five minutes after the minute hand crosses the 1 hour mark.

So in essence, the first time, from Noon, that the hands are in perfect alignment is 65 minutes and 27 seconds later. Then 65 minutes and 27 seconds after that. So on and so forth.

For oppositely aligned, it's the same thing except that it starts approximately 32 minutes and 43 seconds later.

Make sense?

Is that what you wanted?

Time is linear.

Interesting. What I'm looking for is probably calculus or something, but I'd like to see it someday. Why isn't they way you got it absolutely precise? Looks like nice exact small numbers to me. I guess it is a simple matter of 11 divisions of 12 hours as you say, without even any fractions of a section. Wow, Looks like Abraham's got it neatly too -- thanks to both of you.
