How do you solve time sums in geography?
Calculate the location of a place where the local time is noon when it is 7.30 p.m. at Greenwich. Answer: Time difference is 12 – 7.30 = 4.30 or 4 hours 30 minutes = 240 + 30 = 270 minutes So the longitudinal difference is 270/4 = 67.5°. So the longitude is 67.5°W or 67 1/2° W.
What is longitude and time?

What is meant by IDL?
IDL means the International Date Line, which is along 180° E & W. The date or day changes while crossing this line i.e. while there is Monday in the Eastern Hemisphere i.e. 0° – 180°E, there will be Sunday in the Western Hemisphere i. e. 0° – 180° W. Concept: Concept of Longitudes.
What are time zones in geography?
A time zone is one of the areas into which the world is divided where the time is calculated as being a particular number of hours behind or ahead of GMT.
Which lines determine time zones?
The equator is an imaginary circle equidistant from the poles of the Earth. Circles parallel to the equator (lines running east and west) are parallels of latitude….Time Zones.
