Final answer:
Jovian planets include Jupiter, Saturn, Uranus, and Neptune, with a collective total of over 200 known moons. By averaging this number across the four planets, the average number of satellites (moons) around Jovian planets is approximately 50.5, which falls within the range of 30-60 moons per planet.
Step-by-step explanation:
Average Number of Satellites Around Jovian Planets
The question asks about the average number of satellites (moons) around Jovian planets. Jovian planets, also known as gas giants, include Jupiter, Saturn, Uranus, and Neptune. These planets have a large number of moons orbiting around them. For instance, Jupiter has 79 known moons, Saturn has 82, Uranus has 27, and Neptune has 14. Given these numbers, an average can be calculated by adding the total number of moons and dividing by the number of Jovian planets (4). This gives us a total of 202 moons, resulting in an average of 202/4 = 50.5 moons per planet. Therefore, the correct answer is (d) 30-60 moons around Jovian planets.
