Question

It is 11:00 pm at 0 degrees longitude on Monday, 31st December 2020.What will be the time, date and day in a place located at 30 degrees * E longitude?​

Answer 1

Answer:

For every degree there is time difference of 4 minutes.

Lets see how?

360 degree = 24*60 minutes in a day

so 1 degree = 24*60/360 = 4 minutes

Total degree difference between 30 degree west and 30 degree east is 60 degree. So the time difference will be of 60*4 = 240 minutes or 4 hours.

Towards east time is ahead compared to west side. So at 30 degree west time will be 4 hours less than time at 30 degree east.

As time at 30 degree east is 3 pm so at at 30 degree west it will be 11 AM

Answer 2

Answer:

Time at 30degrees east — 3PM — 15:00

Time at 30degrees east — 3PM — 15:00Time at 30degrees west — ?

Time at 30degrees east — 3PM — 15:00Time at 30degrees west — ?Difference in longitudes = 30 +30 = 60degrees

Time at 30degrees east — 3PM — 15:00Time at 30degrees west — ?Difference in longitudes = 30 +30 = 60degrees1 longitude = 4 minutes

Time at 30degrees east — 3PM — 15:00Time at 30degrees west — ?Difference in longitudes = 30 +30 = 60degrees1 longitude = 4 minutesTherefore, Difference in time = 60 × 4 = 240 minutes = 4 hours

Time at 30degrees east — 3PM — 15:00Time at 30degrees west — ?Difference in longitudes = 30 +30 = 60degrees1 longitude = 4 minutesTherefore, Difference in time = 60 × 4 = 240 minutes = 4 hoursSince 30degrees west is at the west of 30degrees east, Therefore time will be deducted.

Time at 30degrees east — 3PM — 15:00Time at 30degrees west — ?Difference in longitudes = 30 +30 = 60degrees1 longitude = 4 minutesTherefore, Difference in time = 60 × 4 = 240 minutes = 4 hoursSince 30degrees west is at the west of 30degrees east, Therefore time will be deducted.Therefore, Time at 30degree West longitude = 15:00 - 4:00 = 11:00 = 11:00 AM
