Answer:
slope = -0.24
Explanation:
First, we need to convert 2.4 miles to feet using the conversion factor of 1 mile = 5280 feet as follows
[tex]2.4\text{ miles}\times\frac{5280\text{ feet}}{1\text{ mile}}=12672\text{ feet}[/tex]
Then, the slope is equal to the ratio of the descending distance to the horizontal distance
[tex]slope=\frac{-3100\text{ ft}}{12672\text{ ft}}=-0.24[/tex]
Therefore, the answer is
slope = -0.24
