Question

A race car can travel at a speed of 3.4 x 10^2 miles/hour. The Speed of Sound is approximately 7.6 × 10^2 miles/hour. How many times faster is the Speed of Sound than the Bullet Train?

Answer 1

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 = $3.4\times 10^2\ mi/h$

The speed of sound = $7.6\times 10^2\ mi/h$

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

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