Answer 1

Answer:

Her actual distance for the trip will be 112.5 miles.

Step-by-step explanation:

You need to analize the information provided in the exercise.

You know that the scale of the map Kelsey is reading is:

$2\ inches=50\ miles$

And according to the exercise, Kelsey's trip measures 4.5 inches on that map.

 Therefore, in order to calculate what will  be her actual distance for the trip (Let be $x$ this distance), you can set up the following proportion:

$\frac{50\ miles}{2\ inches}=\frac{x}{4.5\ inches}$

Finally, you must solve for $x$. Then, you get:

 $\frac{(50\ miles)(4.5\ inches)}{2\ inches}=x\\\\x=112.5\ miles$

 Therefore, her actual distance for the trip will be 112.5 miles
