Q: If it is 3:00 PM in New Delhi (77 degrees East), what time is it in London (0 degrees)?

Solution: New Delhi is 77/15 = 5.13 hours ahead of GMT. Therefore, 3:00 PM - 5.13 hours = 9:30 AM.

Steps: 7

Step 1: Understand that New Delhi is at 77 degrees East and London is at 0 degrees (GMT).
Step 2: Know that the Earth is divided into 360 degrees and it takes 24 hours for a full rotation.
Step 3: Calculate how many degrees correspond to one hour: 360 degrees / 24 hours = 15 degrees per hour.
Step 4: Find out how many hours New Delhi is ahead of GMT by dividing its degrees by the degrees per hour: 77 degrees / 15 degrees per hour = 5.13 hours.
Step 5: Convert 5.13 hours into hours and minutes: 0.13 hours is about 8 minutes (0.13 * 60). So, New Delhi is 5 hours and 8 minutes ahead of GMT.
Step 6: Subtract 5 hours and 8 minutes from 3:00 PM to find the time in London: 3:00 PM - 5 hours = 10:00 AM, then subtract 8 minutes to get 9:52 AM.
Step 7: Therefore, when it is 3:00 PM in New Delhi, it is approximately 9:52 AM in London.
