The Earth rotates about its axis every \(23\) hours, \(56\) minutes, and \(4\) seconds. The radius of the Earth is \(3960\) miles.
What is the linear speed of a point on the Earth's equator (in miles/hour)?
3960 x 2 ==7,920 miles - Earth's diameter at the equator.
Circumference ==Diameter x Pi
Circumference ==7,920 x 3.141592 ==24,881.41 - miles at the equator
Speed ==Distance (Circumference) / Time
4/3600 + 56 / 60 + 23 ==23.93444444......hours taken for 1 full rotation of Earth at equator.
Speed ==24,881.41 / 23.93444..
Speed ==1,039.56 miles per hour.
