Time on Earth
The Earth takes one day to rotate on its axis.
■■ 1 day =24 hours
■■ 1 hour =60 minutes
■■ 24 hours =24\ x\ 60=1440 minutes
■■ The angle of the earth =360 °
■■ 360 °=360 Longitudes
■■ 360 °=1440 minutes
■■ So 1 °=1440/360=4 minutes
■■ In 4 minutes =1° rotation
■■ In 60 minutes = 60/4 = 15° rotation
■■ So, in an hour (60 minutes) the earth rotates 15°
■■ 1 day =24 hours
