Asound wave travels through iron at a rate of 5120 m/s at what rate does the sound wave travel in km/h

Step-by-step explanation:

It is given that, a sound wave travels through iron at a rate of 5120 m/s. We need to convert this speed into km/h.

The speed of the sound wave is given by the product of wavelength and the frequency of the wave.

We know that,

1 km = 1000 m

⇒ 1 m = (1/1000) km

And 1 h = 3600 s

⇒ 1 s = (1/3600) h

5120 m/s = 18432 km/h

Hence, the sound wave travel at the rate of 18432 km/h.
