Chapter 2 Class 6 Geography - Latitudes and Longitudes

What is the relationship between longitude and time? Give examples.



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.
