Vedclass · Answer

(B) The sound travels from the man to the hillock and back to the man to produce an echo.Let $d$ be the distance between the man and the hillock.The total distance traveled by the sound is $2d$.Given,velocity of sound $v = 330\, m/s$ and time $t = 1.5\, s$.Using the formula,$2d = v 	imes t$.$2d = 330 	imes 1.5 = 495\, m$.$d = \frac{495}{2} = 247.5\, m$.Therefore,the distance of the hillock from the man is $247.5\, m$.

$A$ man stands in front of a hillock and fires a gun. He hears an echo after $1.5\, s$. The distance of the hillock from the man is ...... $m$ (velocity of sound in air is $330\, m/s$).
