Question

If you hear a gun shot 1 seconds after it is fired, how far away from the gun are you? (speed of sound in air $=330m{s}^{-1})$

• A. 230 m
• B. 330 m
• C. 430 m
• D. 530 m

Answer 1

Answer: (B)

330 m

$t=\frac{2}{2}s=1s,v=330m^{-1}s,s=?$
We know, $v=\frac{s}{t}$
$\Rightarrow s=v\times t=330\times 1=330m$
