$18432\,km/h$

Step-by-step explanation:

Given: A sound wave travels through iron at a rate of $5120\,m/s$

To find: rate at which the sound wave travel in km/h

Solution:

Use the following units conversions.

$1\,m=\frac{1}{1000}\,km$

$1\,s=\frac{1}{3600}\,h$

Now convert $5120\,m/s$ into km/h

Therefore,

$5120\,m/s=(\frac{5120}{1000})(3600)\\ =512(36)\\=18432\,km/h$
