Answer:
12 times
Step-by-step explanation:
Earth-Moon (EM) = 12⁵ miles
Sun-Mercury (SM) = 12⁷ miles
Sun-Jupiter (SJ) = 12⁸ miles
just FYI, these numbers are only a rough simplification for this example. the real distance are quite a bit different.
so, SJ/SM = 12⁸ / 12⁷ = 12¹ = 12
=> Jupiter is 12 times farther away from the Sun than Mercury.
