$\red {\bold {Here \: is \: your \: answer }}$


$\underline\bold {Answer : 825 \: m}$


$\underline\bold {Given : \: }$


$\bold {Time = 5 \: s }$


$\bold {velocity \: of \: sound = 330 \: m / s}$


$\bold {2d = v \: × \: t}$


$\bold {2d = 330 \: × \: 5}$


$\bold {2d = 1650 }$


$\bold {d = {\frac {1650}{2}}}$


$\bold {d = 825 \: m}$
