Expert Answer:
Given that,
t = 5 sec
v = 330 m/s
Let d is the distance between cliff and siren.
Person heards echo when sound produced by siren gets reflected from the cliff and comes back to the person.
So the total distance travelled by the sound reaching to the person is 2d.
v = 2d/t
2d = vt
d = (330 x 5)/2
d = 825 m
Given that,
t = 5 sec
v = 330 m/s
Let d is the distance between cliff and siren.
Person heards echo when sound produced by siren gets reflected from the cliff and comes back to the person.
So the total distance travelled by the sound reaching to the person is 2d.
v = 2d/t
2d = vt
d = (330 x 5)/2
