If you would like to know how far apart would Dale's house and school be on the map if the scale were 1 inch = 6 miles, you can calculate this using the following steps:
1 inch ... 8 miles
1 1/2 inches = 3/2 inches ... x miles = ?
1 * x = 8 * 3/2
x = 8 * 3/2
x = 12 miles
1 inch ... 6 miles
y inches = ? ... 12 miles
1 * 12 = 6 * y
12 = 6 * y /6
y = 12 / 6
y = 2 inches
The correct result would be C. 2 inches.
