Question

The distance between Milltown and Summerville is 3.5 inches on a map. If the map scale is 1 inch = 20 miles, what is the actual distance between the towns?

Answer 1

70 miles

Steps:
1. Convert the map scale to a fraction: 1 inch/20 miles
2. Convert the map distance to inches: 3.5 inches
3. Multiply the map scale fraction and the map distance: (1 inch/20 miles) x (3.5 inches)
4. Simplify the fraction: 7/20
5. Convert the fraction to a decimal: 0.35
6. Multiply the decimal by the map scale: 0.35 x 20 miles
7. Simplify the product: 70 miles

Answer 2

or, making it simpler

if 1 inch represents 20 miles,
then 3.5 represents 3.5(20) or 70 miles
