Question
With regard to scale, answer the following question:
Convert the statement into R.F. 25 cm on the map = 5 km on ground.
Solution
As, 1 km = 1,00,000 cm
5 km = 1,00,000 × 5 cm
= 5,00,000 cm
Since, R.F. = Distance on the map (in cm)
Distance on the ground (in cm)
R.F. = `25/(5,00,000)` = `1/(20,000)`
Thus, R.F. is 1:20,000
