At stp conditions ([tex]T=0^{\circ}C[/tex]), the speed of sound is
[tex]v=331.2 m/s[/tex]
The sound wave moves by uniform motion, so we can use the basic relationship between space, time and velocity:
[tex]S=vt[/tex]
where S is the distance covered by the sound wave in a time t. In our problem, t=3.00 s, therefore the distance covered by the sound wave is
[tex]S=vt=(331.2 m/s)(3.00 s)=993.6 m[/tex]
