Question

Suppose you are 3.3 km away from rifle range where someone is practicing shooting. How long would it take you to hear the sound of a shot fired by him? (Speed of sound 344m/s)

Answer 1

Answer:

Explanation:

Speed and Distance

Hence, it will take 9.593 seconds to hear the sound of the shot

Explanation:

Given that person is   3.3 km away from rifle range where someone is

practicing shooting

So, distance =3.3 km = 3300 m

Speed of sound is given as 344 m/s

Thus  

Time =  = 9.593 seconds

Hence, it will take 9.593 seconds to hear the sound of the shot

Answer 2

Answer:

9.5930 sec ≈ 9.6 sec

Explanation:

Distance between the places = 3.3 km = 3.3(1000m) = 3300 m

→Speed of sound = (distance/time to cover that distance).

Let the time be 't'

→ 344 = (3300/t)

→ t = (3300/344) s

→ t ≈ 9.5930 s ≈ 9.6 s
