Question

You live in Luckow (India) located at 82*East , your pen friend lives in London, located at 0* (Greenwich Meridian). It is 12 noon at Lucknow what will be the local time in London? Show calculations.

Answer 1

s the earth rotates from west to east, those places that lie east of Greenwich are ahead than the places that lie to the west of Greenwich. The earth rotates 1o in four minute. Thus if Lucknow is located in the east of Greenwich at 820E, we will multiply 82 by 4 which will be 328 minutes or 5 hrs and 28 minutes. Therefore, time at Lucknow is 5 hrs and 28 min. ahead of London (since Lucknow is located to the east of Greenwich). So if the time in London is 12: 00 pm, we will add 5 hrs and 28 minutes to it which will be 5: 28 in the evening.
Therefore, it will be 5:28 pm in the evening when it is 12:00 pm in London.

Answer 2

If the time in Lucknow is 12 Noon then the timing in London would be 5:28 PM.  

As the earth revolves from west to east direction, those areas that endure east of Greenwich are advanced than the countries that lie to the westward direction of Greenwich.  The speed of the earth for rotating is 1 degree for every 4 minutes. Therefore, as Lucknow is located to the east of Greenwich at 820 degree East, we have to calculate the total degree with the timing as; 82 * 4= 328 minutes and thus if we convert this into hours we will find that it is 5 hrs and 28 minutes. That means the timing in London would be 5:28 P.M if the timing in Lucknow is 12 PM.
