Question

A scale on a hiking map shows that 1.5 inches represents 4 miles. What number of actual miles are represented by 6 inches on the map?

Answer 1

16 miles

Explanation

1.5 inches and 6 inches have the same measurement, so we can classify them together.

1/5 × ? =6

If we know that ? is equal to 4, we can do the problem 4 times 4 to get 16.
