Answer 2

Answer:

Average speed of the car is $75.5\text{ miles per hour}$.      

Step-by-step explanation:

We are given the following information:

Distance traveled by the car =

$30\displaystyle\frac{1}{5}\text{ miles}$

Time taken by the car =

$\displaystyle\frac{2}{5}\text{ hours}$

Formula:

Speed = $\displaystyle\frac{\text{Distance covered}}{\text{Time taken}}$

Putting all the values,

$\text{Speed} = \displaystyle\frac{30\frac{1}{5}}{\frac{2}{5}} = \frac{\frac{151}{5}}{\frac{2}{5}} = \frac{151}{2} = 75.5\text{ miles per hour}$

Average speed of the car is $75.5\text{ miles per hour}$.
