The product of the wavelength and the frequency of a wave is the speed at which the wave propagates.
When dealing with radio waves (or all Electromagnetic waves for the matter), the waves propagate at the speed of light (c = 3 E8 m/s).
frequency * wavelength = speed of light
You are given the frequency and want to find the wavelength,
wavelength = speed of light / frequency,
lambda = c / f
Lambda = 3 E8 m/s / 88 E6 s^-1
Lambda = 3.41 meters
The wavelength of the radio wave with frequency 88 MHz is about 3.41 meters long.

Speed = frequency x wavelenth
wavelength = speed of light / frequency
= 3.0 x 10 to the 8th / 88 x 10 to the 6th
= 3.41m
