Question

A boy fires a gun and another boy at a distance of 6120m away hears the sound of firing of the gun, 18 s after its smoke. Find the speed of sound​

Answer 1

Answer:

360

Explanation:

speed=distance/time

s=6120/18

s=360

Answer 2

Answer:

the answer is almost 340 m/ s( approx)

Explanation:

speed of light = 3 x 10 ^ 8 m/s

distance = 6120 m

time = s/ v = 6120/ 3x 10^ 8 s

sound Travels after 18 second so total time taken by sound is 6120/3x 10^ 8 s + 18 s = 18.0000204 s

now v = s/ t

= 6120/ 18.0000204 m/s

= 339.999m/s

=340 m/s ( approx)
