I like using decimals instead of fractions.
1/8: 0.125
So the scale is:
0.125 in: 1.5 mi
What you do to one side you have to do to the other side. We have the map distance, which is 2.5. Let's see what it was multiplied by to find the map distance of their houses.
2.5÷ 0.125= 20
Let's multiply the other side by 20.
20×1.5
30
So, Juanita and Lindsey live 30 minutes away.
