If a plane travels 532 miles in 6 hours, what is its average speed?

To determine the average speed of the plane, you need to use the formula for speed, which is calculated by dividing the total distance traveled by the total time taken.

In this case, the plane traveled a distance of 532 miles over a period of 6 hours. Performing the calculation, you divide 532 by 6:

[

\text{Average Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{532 \text{ miles}}{6 \text{ hours}} \approx 88.67 \text{ miles per hour}.

]

This result indicates that the average speed of the plane is approximately 88.67 miles per hour, which corresponds to one of the choices given.

This value is correct and accurately represents how to find the average speed in a situation involving consistent travel over a given distance and time. Understanding this calculation helps in recognizing the importance of distance and time in determining speed in various real-world situations.
