Answer 1

Her actual distance for the trip will be 112.5 miles.

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:

`(50\ miles)/(2\ inches)=(x)/(4.5\ inches)`

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

`((50\ miles)(4.5\ inches))/(2\ inches)=x\\\\x=112.5\ miles`

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