Question

What total distance will a sound wave travel in air in 3.00 seconds at stp?

Answer 1

At stp conditions ($T=0^{\circ}C$), the speed of sound is
$v=331.2 m/s$
The sound wave moves by uniform motion, so we can use the basic relationship between space, time and velocity:
$S=vt$
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
$S=vt=(331.2 m/s)(3.00 s)=993.6 m$
