Please explain how to solve:
The wavelength of a radio wave is defined as speed divided by frequency. An FM radio station has a frequency of 9 x 10(power of 7) waves per second. The speed of the waves is about 3 x 10 (power of 8) meters per second. What is the wavelength of the station?

just do what it says:
wavelength = 3*10^8/(9*10^7) = 3.333.. or 10/3 or 3 1/3
