Question

Calculate the longitude of a place where the local time is 6:00 a.m., when the time is 9:00 p.m. at New Delhi located at 770 E longitude.

Answer 1

Explanation:

The time difference between the required place and New Delhi is 6 + 9 = 15 hours, so the time in minutes =15 × 60 = 900 minutes So the longitudinal difference = 900/4 = 225°. So the place will be in the west at 225° – 77° = 148° W.
