Answer:
t=266.6 s or 4.4 minutes
Explanation:
The frequency doesn't matter, because light travels at c in a vacuum. All that matters is the distance and the speed of light.
The frequency is the wave to transport what the radio sound so to determinate how long travel must determinate the time take the distance between both
The speed of the radiations is:
[tex]v=3.00x10^8 \frac{m}{s}[/tex]
The distance between Earth and Mars is:
[tex]8.0x10^7 km*\frac{1000m}{1km}=8x10^{10}m[/tex]
So the time is:
[tex]v=\frac{d}{t}[/tex]
[tex]t=\frac{d}{v}=\frac{8x10^{10}m}{3x10^8m/s}[/tex]
[tex]t=266.s[/tex]
or
[tex]t=266.66s\frac{1minute}{60s}=4.4 minutes[/tex]
