Question

a gun was fired 2 kilometres away from a person. The time taken for the sound to reach the person was 4 seconds. Find the speed of sound? ​

Answer 1

Answer:

Speed of sound was 500 m / s.

Explanation:

Here,

Distance between the person and the place where gun was fired is 2 kilometers.

Total time taken for the sound to reach the person is 2 km.

We know,

= > Speed = Distance / time

= > Speed of sound = ( 2 km ) / 4 sec

= > Speed of sound = ( 2 x 1000 m ) / 4 s

= > Speed of sound = 500 m / s

Hence the speed of sound was 500 m / s.

Answer 2

» A gun was fired 2 kilometres away from a person. The time taken for the sound to reach the person was 4 seconds.

Here..

• Distance (d) = 2 km

=> 2 × 1000

=> 2000 m

• Time (t) = 4 seconds

___________ [ GIVEN ]

• We have to find the speed of the sound of the gun.

____________________________

We know that..

» Speed = $\dfrac{Distance}{Time}$

Put the known values in above formula

→ Speed = $\dfrac{2000}{4}$

→ Speed = 500 m/s

___________________________

500 m/s is the speed of the sound.
