Suppose a plane flew east along the equator from the Prime Meridian to the International Dateline; that is, accurately half way around the world. Determine what is its final displacement? Is it the distance covered by its route of flight (12,450 miles) or the distance measured straight through the center of the earth (7,920 miles)? Assume the trip took accurately one day. Calculate the displacement as observed from the Sun?
