Help with a Chemistry question

[From: ] [author: ] [Date: 12-01-17] [Hit: ]
as well as all other electromagnetic waves, travel at the speed of light in space/vacuum at 3.00*10^8 meters/second.8.00*10^7 km = 8.(8.......
How long would it take a Radio wave with a frequency of 7.25 x 10
5 Hz to travel from Mars to Earth if the distance between these 2 planets is approximately 8.00 x 107km?

What formula would I use and why?

Radio waves, as well as all other electromagnetic waves, travel at the speed of light in space/vacuum at 3.00*10^8 meters/second.

8.00*10^7 km = 8.00*10^10 meters

(8.00*10^10 meters) / (3.00*10^8 meters/second) = 266.67 seconds
