Planetary satellites vary greatly in size, from very small, to some that are larger than some planets.
Explanation:
Natural sateletes are celestial bodies that orbit other larger celestial bodies. The solar system has several satellites, the best known being the moon, the natural satellite of planet Earth. The planets of the solar system have different sizes, just like the natural satellites. Thus, there are satellites larger than planets. The moon itself is a larger satellite than some planets, like Mercury.
Ben's average speed was twice Debby's average speed.
Explanation:
Ben covered a total distance of 16 miles (10+4+2) and Debby covered 8 miles (3+2+2+1) which is half of what Ben covered. As they both reached the place in the same amount of time it tells us Ben was faster.
