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 =
<u>To find the distance covered in 1 hour :</u>
Let us assume, 'x' be the distance covered in one hour.
Rate =
<u>Now, comparing the rates to find the x value :</u>
⇒
⇒
⇒
⇒
Therefore, the distance covered in one hour is 76 miles.
