Chapter 6.6, Problem 19E

To determine

To find: The actual distance from the map scale.

Answer to Problem 19E

The actual distanceis 45 kilometres.

Explanation of Solution

Given information :

Consider the information provided, the map distance be 9 centimetres

Calculation:

Assume the distance on map be $x$

distance on the map has a scale of 1 centimetre :5 kilometres and the distance on the map is 9 centimetres Therefore,

The equation is -

  $\begin{array}{l}\frac{1}{5}=\frac{9}{\text{x}}\\ \text{x = 5}\times 9\\ \text{x = 45}\end{array}$

Therefore, the actual distance will be 45 kilometres
