Answer 2

Answer:

radius of the earth ;orbit =1AO=150,000,000 kilometers

circumference of the earth ,s orbit 2*pi*r= 942,000,000 kilometers . the time to complete one orbit = 365.2422 days = 8766 hour speed of revolution = distance / time = 942,000,000 kilometers / 8766 hour = 107,000 kilometers /hour = 30km/sec
