The distance covered in one hour is 76 miles.
<u>Step-by-step explanation:</u>
Edward drives a car for 28.5 miles.
Therefore, the distance he travels by the car = 28.5 miles.
The time it takes to drive 28.5 miles is 3/8 of an hour.
<u>The formula to find the rate :</u>
Rate = Distance traveled / Time taken in hours.
Here, the distance is 28.5 miles and time is 3/8 hour.
Rate = ![28.5/ (3/8)](https://tex.z-dn.net/?f=28.5%2F%20%283%2F8%29)
<u>To find the distance covered in 1 hour :</u>
Let us assume, 'x' be the distance covered in one hour.
Rate = ![x/1](https://tex.z-dn.net/?f=x%2F1)
<u>Now, comparing the rates to find the x value :</u>
⇒ ![28.5 / (3/8) = x /1](https://tex.z-dn.net/?f=28.5%20%2F%20%283%2F8%29%20%3D%20x%20%2F1)
⇒ ![x = 28.5 \times 8/3](https://tex.z-dn.net/?f=x%20%3D%2028.5%20%5Ctimes%20%208%2F3)
⇒ ![x = 228/3](https://tex.z-dn.net/?f=x%20%3D%20228%2F3)
⇒ ![x = 76](https://tex.z-dn.net/?f=x%20%3D%2076)
Therefore, the distance covered in one hour is 76 miles.
