    The time taken for a signal to reach the Earth after it is transmitted from the spacecraft is (500x) seconds

    Explanation:

    Distance of spacecraft from Earth = x AU = x * 149.9*10^6 Km = (149.9*10^6x) Km

    Speed of light = 299,800Km/s

    Time taken for a signal to reach the Earth after it is transmitted from the spacecraft = distance of spacecraft from Earth : speed of light = (149.9*10^6x) Km : 299,800Km/s = (500x) seconds
