What is the distance of the
reflecting surface from the
source, given that the speed of
sound is 342 m s-l?​

Answer 1

Answer:

Step-by-step explanation:

Mark my answer brainlisted

Distance=speed×time/2

=342×3/2

=171*3=513 m

Answer 2

Answer:

Given that:

Speed of sound, v= 342 m/s

And, time of echo= 3s

So,distance= ?

v= 2d /t

2d = vxt

2d= 342×3

2d = 1026

d= 1026/2

d= 513 m

Hence the distance is 513 m..
