How do you find the longitude of a place?
Mark how much distance is between the southern parallel to your location. Add this to the latitude of the southern parallel to get the latitude of your location. To measure the longitude you must place the ruler diagonally on the west and east meridians with the ends of the 2 ½ minute ruler touching both meridians.
What is GMT answer?
Greenwich Mean Time (GMT) is the time measured on the Earth’s zero degree line of longitude, or meridian. This line has been called the Greenwich Meridian since 1884, and it is from here that all terrestrial longitudes are measured and the world’s time zones are calculated.
What is the local time at 45 degrees east longitude?
Since the sun is in the east first before it gets to Greenwich, it is later at 45º East than it is at Greenwich – exactly 3 hours later – so the local time on 45º East will be 15:00 hours, or 3:00 pm. If you say at 45º longitude I assume you are talking about 45º East, otherwise you would have said -45º.
What is the value of 15 degrees longitude?
Every 15° longitude represents one hour’s difference in time: (24 x 15 = 360, the degrees of a circle). You can work out the time at every location on earth if you know how many degrees it is east or west of Greenwich.
What is the time difference between GMT and local time?
From 0° longitude, towards east, time is ahead of GMT. From 0° longitude, towards west, time is behind GMT. So, local time at 45°E, longitude is 1:00 pm, Wednesday, when it is 10:00 am at GMT on Wednesday. So, local time at 45°W, longitude is 7:00 am, on Wednesday, when it is 10:00 am at GMT on Wednesday.
What is the time difference between 8° west longitude and 35° west?
We know that between any two longitudes, there is a time difference of 4 minutes. Therefore, time at 8° West longitude will be 4minutes x 35 = 140 minutes. . 35° longitude lies to the left (West) of 0°, so you will subtract 140 minutes which is equal to 2 Hr. and 20 minutes. Your answer will be 7:00 a.m. – 2 Hr. and 20 minutes. = 4: 40 a.m.
