Q: If it is 3:00 PM in New Delhi (77.2°E), what time is it in London (0° longitude)?
Solution: New Delhi is 77.2°E, which is 77.2 * 4 minutes = 308.8 minutes ahead of GMT. Therefore, 3:00 PM - 5 hours and 8.8 minutes = 9:30 AM in London.
Steps: 9
Step 1: Understand that New Delhi is at 77.2°E longitude and London is at 0° longitude.
Step 2: Calculate the difference in degrees between New Delhi and London. This is 77.2°E - 0° = 77.2°.
Step 3: Know that each degree of longitude represents 4 minutes of time difference.
Step 4: Multiply the degree difference by 4 minutes: 77.2° * 4 minutes = 308.8 minutes.
Step 5: Convert 308.8 minutes into hours and minutes. 308.8 minutes is 5 hours and 8.8 minutes.
Step 6: Since New Delhi is ahead of London, subtract 5 hours and 8.8 minutes from 3:00 PM.
Step 7: Subtract 5 hours from 3:00 PM to get 10:00 AM.
Step 8: Now subtract 8.8 minutes from 10:00 AM. This gives you 9:51 AM.
Step 9: Therefore, the time in London when it is 3:00 PM in New Delhi is approximately 9:51 AM.
