When it is 12 pm at Greenwich What will be the time at 180 degree?
Thus, when it is 12 noon at Greenwich, the time at 15° east of Greenwich will be 15 × 4 = 60 minutes, i.e., 1 hour ahead of Greenwich time, which means 1 p.m. But at 15° west of Greenwich, the time will be behind Greenwich time by one hour, i.e., it will be 11.00 a.m. Similarly, at 180°, it will be midnight when it is …
Why is it 5 30 pm in India when it is 12 noon in the United Kingdom?
This is because the Earth rotates 360 degrees in 24 hours, 1 degree in 4 minutes. The standard meridian of India is 82 degree 30E, and that of London is 0 degree. So when it is 12 noon in London, it is 5.30 pm in India.

How many degrees does the Earth rotate in one hour?
Since the earth is divided into 360º of longitude and one rotation takes 24 hours, it means that in one hour the earth rotates through 15º of longitude. 360/24 = 15. The earth rotates from west to east, so time increases to the east of Greenwich and decreases to the west of the Greenwich meridian.
