Chapter 6, Problem 21CCSR

To determine

To find the distance between Julia’s home and library.

Answer to Problem 21CCSR

2.125 miles.

Explanation of Solution

Given:

On a map, Julia’s home is 8.5 in. from the library and the map scale is 1 in. : 0.25 mi.

Calculation:

The map scale is,

  $\begin{array}{l}1\text{in}\text{.}=0.25\text{mi}\text{.}\\ \Rightarrow \text{8}\text{.5}\text{in}\text{.}=0.25\times 8.5\text{mi}\text{.}\\ \Rightarrow \text{8}\text{.5}\text{in}\text{.}=2.125\text{mi}\text{.}\end{array}$

Therefore distance between Julia’s home and library is 2.125 miles.
