Answer 1

Distance = rate times time.

414= .75x

414/.75

552 miles per hour

Answer 2

Answer: 552 mph

Step-by-step explanation:

The formula to find speed is given by :-

$\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}$

Given : Claire boarded an airplane in Richmond va and flew 414 miles directly to Charleston sc.

Distance = 414 miles.

The total flight time was $\dfrac{3}{4}$ hour.

Then, the speed of Claire's airplane= $\dfrac{414}{\dfrac{3}{4}}$

$=414\times\dfrac{4}{3}=552\text{ mph.}$

Hence, the speed of Claire's airplane= 552 mph.
