The length of Earth’s orbit: The Earth is approximately 93 million miles from the sun. For this exercise we will assume that the Earth’s orbit is a circle.

a. How far does the Earth travel in a year?

b. What is the velocity in miles per year of the Earth in its orbit? (Hint: Recall that Velocity = Distance Time .)

c. How many hours are there in a year? (Note: For this problem ignore leap years.)

d. What is the velocity in miles per hour of the Earth in its orbit?
