उत्तर
Given: R.F. = `1/(10,00,000)`
We want the scale to show distance in miles.
1 mile = 1.609 km = 160934 cm
1 cm on the map = 10,00,000 cm on the ground
= `(10,00,000)/(160934) ≈ 6.21` miles
Let’s take a round number:
Ground distance = 62.1 miles
Map length = `("Group Distance")/("Distance per cm") = (62.1)/(6.21) = 10` cm
Drawing the scale:
Draw a 10 cm long line.
Divide it into 5 equal parts, each = 2 cm.
Each part = `(62.1)/5 = 12.42` miles
Subdivide the first part (leftmost) into 4 sub-divisions, each = `(12.42)/4 = 3.1` miles
Labelling:
Start labeling from 0 to the right: 0, 12.4, 24.8, 37.2, 49.6, 62.1 miles
On the left of 0: 3.1, 6.2, 9.3, 12.4 miles
