I need help,,LOL,, My Daughter Is In NJROTC, She came home from school with homework & Extra Credit, But The Extra Credit Got Us Clueless,LOL,So If You Could Help, PLEASE & THANK YOU,,


The clock faces have hour, minute and second hands and change one hour and two and one half seconds per 15 degrees of longitude,,,

"What is the reason for the 2 1/2 seconds of difference per clock face"
Hint _ Use Math,,,


WE tried to google it cause I have No Clue!!!!!!! And NO Luck,,,

Thank You Colleen,

I just asked my son who is in his first year of JROTC and he said he has no idea..sorry
Is it millitary time?

We have no clue, But the question did come from NJROTC,,,

The earth rotates 15 degrees every hour.

Not a complete answer...I'm trying to figure it out.

I think I got it. A normal clock goes 15 degrees every hour. If this clock goes 1 hour and 2.5 sec. I think it is calculating leap year all the time, instead of adding a whole day every 4 years. I hope this helps.

I suspect that the 2 1/2 seconds is due to the fact that the earth is slightly larger than 24000 miles in diameter. The 2 1/2 seconds would be the "catch up" time based on the circumference of the world. My best guess anyhow, and I reserve the right to be wrong

I thought about it might have something to do with making up time for daylight savings time, but I think that's only a one second difference per 15 degree (time zone)?

Good thinking, cause you'd be CORRECT! :o)

google ZULU time or greenwich time

I think it has to do with time being taken on longitude lines that are true north and south and not magnetic north and south

I had to first look up what NJROTC was...ok I am blonde get over it!

There are 25 integer World Time Zones from -12 through 0 (GMT) to +12. Each one is 15° of Longitude as measured East and West from the Prime Meridian of the World at Greenwich, England. Some countries have adopted non-standard time zones, usually 30 minutes offset which have a * designation.

Longitude consists of 180 to -180 east and west. 375 total longitude divided by 15 comes to 25 or 2.5 seconds.

I know that I should know, but unfortunately my knowledge is not knowledgeable to knowingly answer this in a knowing way.

Very impressive. Bravo!!

Thank You Everybody,We are Gonna Go With The Captain & Timmyschillen,, Thank You,,I'll Let You Guys Know How She Did By The End Of The Week,, Thanks Again,,,,

Or, could you say that 24 rotations of 15 degrees each will equal 360 degrees...and 24 rotations times 2.5 seconds will equal one hour?

I BELIEVE THAT I HAVE IT.....it deals with navigation and time displacement...
it may seem like science fiction but it is indeed science fact...
we are talking about the navy..latitudes..longitudes..the oceans
due to the effects of the gravitational pull of the moon...time,it seems is slightly more elevated ont he oceans and high seas..then on land...

i believe i am right

but then it is just a theory..time distortion does exist..it has been scientificly proven..durring the detonation of the first atomic bomb in new mexico...but will this effect the oceans?
and the matter of how time is displaced?..

To everybody that help us last night,,, My daughter took the help from, The Captain & Timmyschillen, And She got it wrong,,
Her girlfriend Maire took Kolhauszer answer and got it right,,,

Thank You All,,, ~~ColleenAnn~~

it was hard at first...but what had to be figured out..was not really why the time is displaced..but how..

if time can be displaced..as einstein proved back in 1946..and there are forces in nature that makes the atomic bomb seem as a
pindrop in a well by comparison...then it would seem plausible that some forces of nature as well does have the ability to cause time to alter .

to be honest i joined two theories into one to come up with my own..

when the,,CONSTANT..of the problem was resolved,,then the answer was always there..

but hey..thanks for the kodos..

You are the best! Not just another pretty face....A smart, handsome one.
