To find the scale factor of Jupiter to Earth, you can divide the circumference of Jupiter by the circumference of Earth.
Circumference of Jupiter: 272,946 miles
Circumference of Earth: 24,901 miles
Scale Factor = Circumference of Jupiter / Circumference of Earth Scale Factor = 272,946 / 24,901 ≈ 10.95
When rounded to the nearest whole number, this gives us approximately 11.
Therefore, the scale factor of Jupiter to Earth, rounded to the nearest whole number, is 11:1.
