The Earth is one astronomical unit from the sun i.e.1AU= 93 million miles.The angular speed is 0.9863 degrees a day. How many revolutions will the Earth make in one hour?

Question

The linear speed in miles per hour for this question is 66711.7, but I can not figure out how to find how much of a revolution the earth will make in an hour.

Answer 1

0.9863° / day

0.041° / hour divide by 24

C = 2(π)(93) C represent one revolution (orbit) in millions of miles

C(0.041° / 360°) equals part of revolution in one hour.
