Chapter 6.6, Problem 18E

To determine

To find:The actual distance from the map scale

Answer to Problem 18E

The actual distanceis 100 kilometres

Explanation of Solution

Given information :

Consider, the map distance be 20 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 20 centimetres Therefore,

The equation is -

  $\begin{array}{l}\frac{1}{5}=\frac{20}{\text{x}}\\ \text{x = 5}\times 20\\ \text{x = 100}\end{array}$

Therefore, the actual distance will be 100 kilometres
