(B) The distance between the person and the building is $d = 167 \ m$.The sound travels to the building and reflects back to the person,covering a total distance of $2d = 2 	imes 167 \ m = 334 \ m$.The speed of sound is given as $V = 334 \ m \ s^{-1}$.The time taken to hear the echo is calculated using the formula $t = \frac{	ext{Total Distance}}{	ext{Speed}} = \frac{2d}{V}$.Substituting the values: $t = \frac{334 \ m}{334 \ m \ s^{-1}} = 1.0 \ s$.Therefore,the person hears the echo after $1.0 \ s$.

$A$ person fires a gun in front of a building $167 \ m$ away. If the speed of sound is $334 \ m \ s^{-1}$,calculate the time in which he hears an echo. (in $s$)
