Plane travels 1000 miles in 5 hours and 30 minutes. What is the average speed of the plane in 1 hour?

285.7 miles per hour

Step-by-step explanation:

You would set up 2 equations that are equal to each other, and solve for the missing quantity. IN this case we are missing the distance for the average, so we'll call that d. This is how you set it up;

d / t = d / t

1000miles / 5.5hrs = d / 1hr

Solve for time, and you get 285.7 Miles per hour
