Answer :

The International Date Line is at 180 ̊. At 15 ̊ E, the time is 10 A.M on Wednesday.


The earth rotates 360° in 24 hours, which means 15° in 1 hour.


360° = 24hours, then 360°/24hours = 15°.


Therefore in 1° the earth takes 4 minutes.


60minutes/15° = 4 minutes. 1° = 4 minutes


Movement from 15 ̊ E to 180 ̊ E = 165 ̊


Change in time = 165*4 = 660 minutes = 660/60 = 11 hours


Time at IDL = 9 p.m
