Question

What would be the local time date at Kolkata 88°30'E , while it is we'd ,8:30 pm on December 31 ,2014 at New York​

Answer 1

Answer:

Longitude of Greenwich - 0°

Longitude of Kolkata - 88°30′ E = 88.5° E

Difference in Longitudes = 88.5 - 0

= 88.5

1 degree longitude = 4 minutes

Therefore, 88.5 degrees longitude = 88.5 × 4 = 354 minutes = 354/60 = 5 hours 54 minutes

Difference in Time = 5 hours 54 minutes

Since, Kolkata is at the east of Greenwich, therefore, time will be added.

Therefore, time at Kolkata = 11:30 + 5:54 = 16:84 = 17:24 = 5:24 PM

NOTE - This is the local time of Kolkata. The whole nation follows the Indian Standard Time(IST), time at the longitude 82°30′ E.
