Answer: 515 MPH

Step-by-step explanation: To determine the plane's average speed, we can use the formula:

Average speed = Total distance ÷ Total time

In this case, the total distance is given as 1,416.25 miles and the total time is given as 2.75 hours.

So, by substituting these values into the formula:

Average speed = 1,416.25 miles ÷ 2.75 hours

Simplifying this calculation, we find:

Average speed ≈ 515 mph

Therefore, the plane's average speed is approximately 515 mph.
