Final answer:

Luciana can run approximately 7.273 miles in an hour.

Step-by-step explanation:

To determine how many miles Luciana can run in an hour, we need to find the proportion between the time she can run 3 miles and the time of an hour. We can set up a proportion using the formula:

(3 miles / 24.75 minutes) = (x miles / 60 minutes).

Solving for x, we can cross multiply and divide to find

x = (3 miles * 60 minutes) / 24.75 minutes

= 7.273 miles.
