Question
If it is 12 noon at 60°E longitude, then explain what would be the time at 30° W longitude?
Answer in Brief
Solution
- The difference between 60° E longitude and 30° W longitude will be of 90 degrees. (The difference of 60 degrees between 0° and 60° E + the difference of 30 degrees between 0° and 30° W = 90 degrees.)
- Difference in local time = 90 × 4
= 360 minutes
= 360 minutes ÷ 60 minutes = 6 hours. - Longitudes lying to the east of any longitude are ahead of the time of that longitude while those lying to the west are behind.
- Therefore, if it is 12 noon at 60° E longitude, then it would be 6 a.m. at 30° W longitude, (behind by 6 hours)
