Draw a liner scale, R. F=1:100000. Primary division 2 mile and secondary division half mile.
Understand the Problem
The question is asking us to create a linear scale with a specific representative fraction (R.F) of 1:100000. It specifies that the primary divisions of the scale should represent 2 miles, and the secondary divisions should represent half a mile. We will need to determine the scale length based on these divisions and format it properly.
Answer
Draw a scale where 2 miles is 3.2 cm and 0.5 miles is 0.8 cm on the line.
To draw a linear scale with R.F. 1:100,000, mark a line representing the scale. Set primary divisions to represent 2 miles each; each primary division should measure 3.2 cm on paper (since 1 mile on ground equals 1.6 cm on paper with this R.F.). Split the primary divisions into secondary divisions representing 0.5 miles, which would be 0.8 cm each.

More Information
A linear scale visually represents distances directly on a map, making it easier to understand scale without having to calculate conversions from a representative fraction.
Tips
Be sure to measure accurately according to the scale when marking your primary and secondary divisions to reflect ground distances correctly.
