Question

A hammer is struck hard on a railway line. How far will the sound travel in 2.5s? Assume the velocity of sound in iron is 5100m/s.

Answer 1

Answer:

about 12750 m

Explanation:

because distance = speed * time.. speed = 5100m/s and time is 2.5 so 5100*2.5= 12750m

Answer 2

The distance covered by the sound wave is 12750 meters.

Explanation:

It is given that :

Velocity of sound in iron is 5100 m/s, v = 5100 m/s

We need to find the distance traveled by the sound wave in 2.5 seconds. Speed of a wave is equal to the distance covered by wave per unit time.

$v=\dfrac{d}{t}\\\\d=v\times t\\\\d=5100\ m/s\times 2.5\ s\\\\d=12750\ m$

So, the distance covered by the sound wave is 12750 meters. Hence, this is the required solution.
