The earth take 365.25 days to orbit the sun. What is it's relative speed to the star in days? hours?

Hint: v=d/t

distance = 360 degrees and the time = 24 hours=1 day

Calculate the circumference using D of 16 millions miles and pi C=50.3 million miles. Using your hint v = (50.3 10^6) / (365.25 x 24 hrs)

radius of 98 million miles or a diameter of 196 million miles, giving a circumference of 615.75 million miles using the d=rt equation,

v=615.75 million / (365.24 days) = 1.69 million miles per day, or. 07 million miles per hour.
