Question

A sound wave travels 2000m in 8 s. What is the velocity of sound?

Answer 1

Answer:

250 m/s

Explanation:

Displacement = 2000 m

Time = 8s

Therefore , Velocity

= displacement / time taken

= 2000 m / 8 s = 250 m/s

Answer 2

The velocity of the sound is 250 m/s.

• Given data :

The given sound wave travels 2000 metres of distance in the time of 20 seconds.

• And,we have to calculate the velocity of the given sound wave.

• Now, we know that the velocity of an object is the distance covered by that object in single unit time (1 hour / 1 minute / 1 second).

• So,the velocity of the given sound wave =

The sound wave travels in 8 seconds a distance of = 2000 metres

The sound wave travels in 1 second a distance of = 2000/8 = 250 metres.

• So,the velocity of that given sound wave is 250 m/s. (Answer)
