and yet, I can see this as correct at the same time.
On a grand scale, consider this.
Let's say it takes the same amount of time for Mercury to make one full revolution around the sun as it does Neptune. (I know this is NOT true, but for the example...)
(Mercury is closest to the sun, Neptune is farthest).
They both take X amount time to get around one full revolution.....
Which planet was moving faster? Take a 1/4 of the distance of each planet, and measure that speed. You'd think if Neptune had to travel SOOO much more distance in the same amount of time, wouldnt' it be traveling faster?
But at the same time, they end at the same points, at the same time, yet Neptune travel milliions of miles farther.....
