Answer 1

Answer:

Step-by-step explanation:

Grocery Store

12 mi / 3 cm = x / 2.5 cm            Cross multiply

12 * 2.5 = 3 * x                             Multiply

30 = 3x                                        Divide by 3

30/3 = x

x = 10 miles

Library

12 mi / 2 cm = x / 1.5                  Cross multiply

12 * 1.5 = 2x

18 = 2x                                        Divide by 2

18/2 = x

9 miles

The library is closer than the grocery store.
