343 meters per secondThis is not a good answer, because someone too forgot to tell us the important temperature, and the given atmospheric pressure "at sea level" makes really no sense. In SI units with dry air at 20°C (68°F), the speed of sound c is 343 meters per second (m/s).
u copied it from the google.
I will report it!

The speed of sound is calculated by using the formula V=√γP/√ρ
Where γ is the ratio of constant pressure and constant volume i.e=Cр/Cv=1.402
and rho is the density of the medium in which the sound waves are travelling or simply by using the formula V=υλ.
The speed of sound in air at 20°C is 331.2 m/sec and at 0°C it is 344 m/sec
I hope u got it!
