Chapter 6.6, Problem 22E

To determine

To find : The distance on the map which has a scale of 1 inch : 3 kilometres .

Answer to Problem 22E

The distance on map will be $25.33$ km.

Explanation of Solution

Given information:

Consider the actual distance be 76 km.

Calculation :

Assume the distance on the map be ‘ $x$ ’.

distance on the maphas a scale of 1 inch : 3 km and the actual distance be 76 km.

Therefore,

The equation will be-

  $\begin{array}{l}\frac{1}{3}=\frac{x}{76}\left[\text{use cross multiplication property}\right]\\ 3x=76\\ x=\frac{76}{3}\left[\text{Divide}\right]\\ x=25.33\end{array}$

The distance on map will be $25.33$ km.
