Question

If it is 11 am at Greenwich London, what will be the time at 40 degree East of Greenwich? ​

Answer 1

Answer:

❥Solution :-

• The Earth rotates once in 24 hours. From that we can write one equation.
• 360°=24 hrs, 1°=?=(24÷360)=0.0667 hours= 4 minutes.
• That means Earth rotates distance of 1° in 4 minutes. So, to rotate 30 degrees it will require 120 minutes or 2 hours more.
• The place towards East of Greenwich will have time ahead of Greenwich and western place will have time before as Earth rotetes east to west.
• So, Time at 30°E=120 minutes more than 10 am
• =12 noon
• Time at 20° W= 20×4=80 minutes less than 10 am
• = 8:40 am
