Chapter 6.6, Problem 5E

To determine

To find:The actual distance from the map scale.

Answer to Problem 5E

The actual distanceis1280miles.

Explanation of Solution

Given information :

Consider, the map distance be 32inches

Calculations:

Assume the actual distance on be $x$ .

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

32inches Therefore,

The expression will be-

  $\begin{array}{l}\frac{1}{40}=\frac{32}{\text{x}}\\ \text{x = 40}\times 32\\ \text{x = 1280}\end{array}$

Therefore, the actual distance will be 1280miles
