$\frac{3}{25}$
The slope measures the ratio of the vertical change to the horizontal change between 2 points on a line. We can write the slope as m= (vertical change)/(horizontal change) In this example, the vertical change of the plane is 3 miles and the horizontal change is 25 miles. Therefore, $m=\frac{3}{25}$
