Sagot :

Answer:

The speed of sound is 2.23 times of the speed of race car

Step-by-step explanation:

Given that,

The speed of a race car = [tex]3.4\times 10^2\ mi/h[/tex]

The speed of sound = [tex]7.6\times 10^2\ mi/h[/tex]

Dividing the speed of sound to the speed of a race car. So,[tex]\dfrac{\text{speed of sound}}{\text{speed of race car}}=\dfrac{7.6\times 10^2}{3.4\times 10^2}\\\\\dfrac{\text{speed of sound}}{\text{speed of race car}}=2.23[/tex]

So, the speed of sound is 2.23 times of the speed of race car.
