Answer:

$2.28*10^{3}\frac{mi}{h}$

Step-by-step explanation:

Let

x-----> the speed of sound in miles per hour

y----> the speed in Match 3

we know that

$y=3x$ -----> equation A

$x=7.6*10^{2}\frac{mi}{h}$

Substitute the value of x in the equation A

$y=3(7.6*10^{2}\frac{mi}{h})=22.8*10^{2}\frac{mi}{h}$

$22.8*10^{2}\frac{mi}{h}=2.28*10^{3}\frac{mi}{h}$
