A man fires a bullet standing between two cliffs

Asked by admin @ 16/08/2021 in Math viewed by 323 People

A man fires a bullet standing between two cliffs. first echo is heard after 3 s and the second echo is heard after 5 s. if the velocity of sound is 330 m/s, then please help me to calculate the distance between the cliffs.

Answered by admin @ 16/08/2021

First distance = d1
Second distance = d2
BTP,
d1 = (v×t)/2
(330×3)/2 = 495m

d2 = (v×t)/2
(330×5)/2 = 825m

.°. Total distance = d1+d2 = (495+825)m=1320m

Answer. The total distance between the cliffs is 1320m.
