Question

Calculate the local time of Singapore (104°E) when it is 6:00p.m at Greenwich.​

Answer 1

Answer:

Clues and answer:

As 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 1° in four minute.

Thus if Singapore is located in the east of Greenwich at 104°E, we will multiply 104 by 4 which will be 416 minutes or 6 hrs and 56 minutes.

Singapore is 6 hrs and 54 minutes ahead of Greenwich because Singapore is located to the east of Greenwich.

Time of Greenwich is 6: 00 PM, so add 6 hrs. 54 minutes to it (6:00 + 6:54 = 12:54). The time is 00:56 AM the next morning in Singapore.
