Chapter 6.6, Problem 4E

To determine

To find:The actual distance from the map scale.

Answer to Problem 4E

The actual distanceis480miles

Explanation of Solution

Given information :

Consider the information provided, distance is 12inches.

Calculation:

Assume the actual distance on be $x$

distance on the map has a scale of 1inch:40miles and the distance on the map is

12inches Therefore,

The expression will be-

  $\begin{array}{l}\frac{1}{40}=\frac{12}{\text{x}}\\ \text{x = 40}\times 12\\ \text{x = 480}\end{array}$

Therefore, the actual distance will be 480miles
