Question

The scale of a town map is 1 inch to 4 miles. On the map, the park and the airport are 6 inches apart. What is the actual distance between the park and the airport?

Answer 1

1/4 = 6/x --- (1 in to 4 mi = 6 in to x mi)
cross multiply
(1)(x) = (4)(6)
x = 24 miles

Answer 2

1 inch = 4 miles
6 inches = x miles
6 * 4 = x
x = 24 miles

Answer 4

you used proportions and I just used given data and we both got the same answer. There are often quite a few ways to get an answer to an equation using algebra.
