The discussion centers on calculating the time it takes for a radio wave to travel from Mars to Earth, given a frequency of 7.25 x 105 Hz and a distance of approximately 8.00 x 107 km. The key insight is that the frequency of the radio wave is irrelevant to the calculation. The correct approach involves using the speed of light in a vacuum, which is approximately 3.00 x 108 m/s, to determine the travel time. The final calculation yields a travel time of approximately 266 seconds.

How long would it take a radio wave whose frequency is 7.25 x 10^5 Hz to travel from Mars to Earth if the distance between the two planets is approximately 8.00 x 10^7 km.
Homework Equations
Don't know what to put here.
The Attempt at a Solution
7.25 x 10^5 / 8.00 10^9=9.0625 x 10^-5
Is that they right answer or am i doing this whole thing the wrong way?
