Answer:
Answer by Student
-
The relationship between longitude and time is that
local time varies with longitude
due to the Earth’s rotation and position in relation to the Sun.
-
A
difference of 15° longitude corresponds to a one-hour difference
in
local time,
or a difference of 4 minutes for each degree of longitude.
-
Places
east of Greenwich gain time,
while places
west of Greenwich lose time
.
- For example , New Delhi (77.2°E) is 5 hours and 30 minutes ahead of Greenwich (0°), while Ottawa (75.7°W) is 5 hours behind Greenwich. This means that when it is noon in Greenwich, it is 5:30 PM in New Delhi and 7:00 AM in Ottawa.
