ANSWER:Solution Step 1 of 6 In order to see the sun as static on the equator of the earth in a plane. The plane must have the speed same as that of the earth. Which means the plane should also complete one full revolution around the earth in the same time as earth completes one rotation about its axis of rotation; one complete revolution or rotation in 24 hours.
