For graphical scale, to know the length of the line we need to make following calculations. 1:50,000 means 1 unit on map represents 50,000 units on ground.
In this way, 1 inch = 50,000 inches
6 inches = 50000 × \(\frac{6}{63360}\)
6 inches = 4.73 miles
Since 4.73 miles is not an integer, therefore we take 5 as an integer on number line. Now we need to make following calculations to present number line as 5 miles.
Since 6 inches = 4.73 miles
Therefore 5 miles = 6 × \(\frac{5}{4.73}\)
5 miles will be represented by 6.34 inches.
We can make the graph by following steps:
First of all draw a 6.34 inches line and divide it in 5 important parts. Except one part from the left, let us give all parts a distance of 1.268 inch. Now divide the first part in 4 equal parts and each part will be equal to 0.32 inch.
