Question

The scale on a map shows that 2 inches represents 15 miles. Which proportion can be used to find the actual distance, x, represented by 30 inches on the map?

Answer 1

2 / 15 = 30 / x.....2 inches to 15 miles = 30 inches to x miles

could also be :

15 /2 = x/30...15 miles to 2 inches = x miles to 30 inches

either way, u will get the same answer
