Question

When it is 12 noon on Monday at Greenwich, what is the local time in Tokyo with 140 degree East?

Answer 1

Answer:

Explanation:

The location is not very important. Tokyo is in the Japan Standard Time Zone, and it’s 9 hours ahead of UTC (and thus GMT), so the local time will be 21:00 JST on Monday

Answer 2

Answer: 9:20 pm on Monday

Explanation: Since Greenwich is at 0 degrees longitude, there are 140 longitudes between Tokyo and Greenwich.

time difference= 140 multiplied by 4; as there are 4 mins for 1 degree of longitude = 560 mins or 9 hours and 20 mins

Since Tokyo is to the East of Greenwich, this number is added to 12 (noon)

= 12:00 pm + 9:20

Thus, it is 9:20 pm in Tokyo on Monday.
