Question

A scale on a hiking map shows that 1.51.51, point, 5 inches represents 444 miles. What number of actual miles are represented by 666 inches on the map? miles

Answer 1

The answer to the question is

16 actual miles

Explanation:

To solve the question first we note that

1.5 inches on map = 4 actual miles

This means that, dividing both sides by 1.5 we have

1 inch on the map is equal to
`(4)/(1.5)` actual miles

Which indicates that 6 inches on the map will be 6×
`(4)/(1.5)` =
`(6)/(1.5)`×4actual miles

which is 4 × 4 or 16 actual miles as 6÷1.5 = 4
