Thank you for the opportunity to help you with your question!

The avarage distance from the sun is 1.496 x 10^11 m , it depends on which figures you understand(Earth's orbit is not perfectly circular so we approximate)

Time =

we start with finding the time and speed

radius of Earth's path

(r = 150,000,000 km)

time = 365daysx24*3600

=31,536,000

circumference of the earth =

c= 2rπ Distance= 942,000,000 km speed = distance /time

942,000,000/31,536,000 SPEED = 29.87 km/s

OR

(1.496 x 10^11m)/(31,536,000)
