The speed of the sound (s) is determined by multiplying the wavelength (λ) by the given frequency (f). 
                                      s = (λ)(f)
                                      s = (1.3 m)(266/s) = 345.8 m/s
Thus, the speed of sound is approximately equal to 245.8 m/s. 

The answer is 346 in edge
