how do u count time by longitudes and latitudes?

Question

i need the ans for geography

Answer 1

Each line of longitude ( lines that run north-south ) is a 15 minute difference. Starting with the line line the runs through Greenwich England, which is 0 hours, going west over the Atlantic Ocean you add 15 minutes for each line of longitude. Latitude lines ( running from east-west and are of varying lengths ) have nothing to with time. If you wanted to say this, they help determine or quantify the weather in similar regions. Land masses in the same latitudes will have similar temperature patterns.

Answer 2

You do not count time by latitude which is a measure of your distance from the equator. Time. clocks and counting were all involved in the invention of longitude. It is a fascinating story
http://en.wikipedia.org/wiki/Longitude
Sailors (despite modern urban myths) were always able to measure north south movement (how far from the equator) by measuring the declension (angle) of the sun to the horizon. But it was difficult to figure a way to measure east-west distance from a given point. When mechanical clocks were developed, it was realized (after many, many trials) that if you set a clock to a time at a given point (in this case it was Greenwich England (home of the Royal Society that had offered a prize to whomever could develop a system of measuring longitude) and kept the clock working on that set time (Greenwich mean time) then by calculating the difference between "natural " time where ever you are (the position of the sun in the sky) and the Greenwich time you could figure your distance from Greenwich in degrees and minutes. Thus the different time zones in the world all measured from Greenwich mean time where the prime meridian (zero degree) "runs" around the earth.So in answer to your question 15 degrees of longitude equals one hour of time or roughly one time zone.

Answer 3

Every Latitude to the east takes you 1/4 an hour ealier & every latitude to the west takes you 1/4 an hour More .Longtitudes don't count

For eg .

Adam is 1 latitude east of Belle
then when adams time is 12:00PM , Belle's is 11:45 Am

Adam is 1 latitude west of Belle
then when adams time is 12:00PM , Belle's is 12:15 Pm

Answer 4

Well, its pretty easy so i'll let you do it yourself. Since the our planet is round, there are 360 degrees (a complete circle) and one day is composed of 24 hours. So make a rule of 3 If every 24 hours the planet makes one full rotation (the planet rotates the whole 360 degrees), then in 1 hour how many degrees does it rotate? so multiply 360 degrees times 1 hour= 360 degrees and divde it by 24 hours= 15, so every hour the would rotates 15 degrees.

Answer 5

hi pooh.
k,first of all for finding out the time approximately,the longitude of the place is enough,but if we want to know the accurate time then we require latitude
For ex... take longitude 075degress 15mins w
then divide 75 by 15 it gives u 5hrs of time
then 15 mins of long gives u 1 min by time
there fore u got 5hrs and 01 mins since we are west u add this to greenwich time to get ur time.....
the rule is that the 360degrees of earth divide by 24hrs giving u the rule as mentioned by ppl in this forum...[ THIS ALSO TELLS U THAT THOSE WHO ARE IN THE EAST LONGITUDE THEY ARE AHEAD IN TIME THAN THOSE IN THE WEST]

but we require to know greenwich time for this,if dont have this data then we can find out by using the sun which involves declination and GHA values ,which ill tell tell if u want ti know...

Answer 6

lol, it aint the real "time"

they use minutes for precise measurements, but you cant tell time from it
