speed =distance /time
distance =speed *time
d=v*t
d=342*3
d=1026
the distance is travelled by eco so 1026/2=513

Speed of sound,
V = 342ms-^1
Time taken for listening the echo,
t = 3s
Distance travelled by the sound
= V x t
= 342ms-^1 x 3s
= 1026 m
In 3 s sound has to travel twice the distance between the reflecting surface and the person.
Therefore the distance between the reflecting surface and the person
= 1026 m / 2
= 513 m.
V = 342ms-^1
Time taken for listening the echo,
t = 3s
Distance travelled by the sound
= V x t
= 342ms-^1 x 3s
= 1026 m
In 3 s sound has to travel twice the distance between the reflecting surface and the person.
Therefore the distance between the reflecting surface and the person
= 1026 m / 2
= 513 m.
