Question 4

The distance between New Delhi Station and Safdarjung Enclave bus stop is 20 km. On the map of Delhi, it has been shown by a line of 3.5 cm. Draw the linear scale of the map and calculate the R.F.

Answer

According to the given question,
The scale is 3.5 cm to 20 km = 3.5 cm to 20,00,000 cm
(Since 1 km = 1,00,000 cm)
R.F. = Distance on the map / Distance on the ground
R.F. = 3.5 / 20,00,000
R.F. = 1 : 571428.57
R.F. ≈ 1 : 571429
