At what rate does the sound wave travel in \dfrac{\text{km}}{\text{h}} h km ​ start fraction, start text, k, m, end text, divided by, start text, h, end text, end fraction? \dfrac{\text{km}}{\text{h}} h km ​

Accepted Solution

A:
Answer:18432 km/hStep-by-step explanation:It is given that a sound wave travels through iron at a rate of 5120 m/s.We know that1 km = 1000 m1 hour = 60 minutes1 minutes = 60 secondUsing these conversions we get1 m = 0.001 km1 hour  = 3600 second[tex]5120\text{ m/s }=5120\times 0.001\times 3600\text{ km/h}[/tex][tex]5120\text{ m/s }=18432\text{ km/h}[/tex]Therefore, the sound wave travels through iron at a rate of 18432 km/h.
