Question
With regard to scale, answer the following questions:
Convert the statement into R.F. `2 1/2` inches on the map = 5 miles on ground.
Solution
`2 1/2` inches on the map = 5 miles on ground
As, 1 mile = 63,360 inches
5 miles = 63,360 × 5 inches
= 3,16,800 inches
Since, R.F. = Distance on the map (in inch)
Distance on the ground (in inch)
R.F. = `2.5/(3,16,800)` = `1/(1,26,720)`
Thus, R.F. is 1:1,26,720
