Question

calculate the time 30 degree west 82.8 30 degree east longitude when it is 3pm at greenwich​

Answer 1

Answer:

11Am

Explanation:

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.
