to work out distance between greenville and north valley:
4.5 x 20 = 90 miles apart

to work out the distance on krystal's map:
90/18 = 5
so the distance from greenville to north valley on Krysatl's map is 5 inches

Answer: 5 inches


Step-by-step explanation:

Given: On Carrie's map, Distance from Greenville and north valley=4.5 inches

The scale of her map is 1 inch = 20 miles

Then the original distance between Greenville and north valley[tex]=4.5\times20=90\ miles[/tex]

Since, the scale on Krystal's map is 1 inch=18 miles.

Then the distance from Greenville to north valley on Krystal's map[tex]=\frac{90}{18}=5\ inches[/tex]

Hence, on Krystal's map Greenville and north valley are 5 inches apart.
