Speed = distance/time
so time taken = distance/speed

Time = 3.54x10^7 / 3x10^8
Time = 0.118 seconds

The time taken by radio signal to reach on earth is 0.118 second.

The relation between distance , time and speed is given as,

[tex]Distance=speed * time\\ \\ time=\frac{Distance}{Speed} [/tex]

Given that, Speed of radio signal is [tex]3*10^{8} m/s[/tex] and Distance between satellite and earth is [tex]3.54*10^{7} m[/tex].

The time taken by radio signal to reach on earth is,

[tex]time=\frac{3.54*10^{7} }{3*10^{8} } =0.118s[/tex]

Therefore, The time taken by radio signal to reach on earth is 0.118 second.
