An X-ray telemetry burst from an automated scientific explorer near a moon of Jupiter takes 444444 minutes to reach an Earth-orbiting observatory.
A radio beacon transmission from a lunar scientific outpost takes 1.321.321.32 seconds to reach the same observatory.
Calculate how many times further the Jupiter explorer is from the observatory than the lunar outpost.
State the fundamental property of electromagnetic waves that you used to make this calculation.
