A sound wave travels through iron at a rate of 5120\,\dfrac{\text{m}}{\text{s}}

Question

At what rate does the sound wave travel in \dfrac{\text{km}}{\text{h}}?

Answer 1

First, let's convert the speed of sound in iron from meters per second to kilometers per hour.

There are 1000 meters in 1 kilometer.
There are 3600 seconds in 1 hour.

So, to convert the speed of sound in iron from meters per second to kilometers per hour:

5120 m/s * (1 km / 1000 m) * (3600 s / 1 hr) = 18432 km/hr

Therefore, the sound wave travels through iron at a rate of 18432 \, \dfrac{\text{km}}{\text{h}}.
