If it is 3:00 PM in New Delhi (77°E), what time is it in London (0° longitude)?

Step 1: Understand that New Delhi is at 77°E longitude.
Step 2: Know that each degree of longitude represents 4 minutes of time difference from GMT (Greenwich Mean Time).
Step 3: Calculate the time difference: 77 degrees * 4 minutes = 308 minutes.
Step 4: Convert 308 minutes into hours and minutes: 308 minutes = 5 hours and 8 minutes.
Step 5: Since New Delhi is ahead of GMT, add the time difference to GMT to find the time in New Delhi.
Step 6: If it is 3:00 PM in New Delhi, subtract the time difference (5 hours and 8 minutes) to find the time in London.
Step 7: Calculate 3:00 PM - 5 hours = 10:00 AM, then subtract 8 minutes to get 9:52 AM.
Step 8: Therefore, the time in London is 9:52 AM.
