Question

find out the R.F. when the scale is 0.6 inches to 1 mile​

Answer 1

Explanation:

on a map with the scale 1:20000,

3 centimeters accord to 0.6 kilometers in reality.

1 cm ⇒ 20000 cm

3 cm ⇒ 20000 * 3 cm = 60000 cm = 600 m = 0.6 km

The scale is rounded to integers, the distance of the map to 0.1, the real distance to 0.001.

Answer 2

0.6 inches represents = 1 mile or 63360 inches

0.6 inches represents = 63360

then 1 inch represents = 63360/0.6

Which is = 105600

Therefore RF = 1 : 105600

Explanation:

• A "Representative fraction" is a ratio/fraction which "expresses" the "mathematical relationship" between "Land's actual length & length on the Map" such as 1:25000 & is "indicated" by a "fraction" whose "numerator" is "1" always. This "fraction" is generally "abbreviated" as "RF". Therefore,
• "Representative Fraction" (RF) = "Map distance/Ground distance"
• The measurement unit of "distances"in  the "denominator & numerator" is the "same". for example, if we say RF of a map is 1/200000 or 1:200000, it implies that 1 unit on the"map" "represents 200000 units on the "ground". If the measurement unit say is CM, we would say 1cm on the "map" "represents" 200000 cms on the "ground". Similarly if the measurement unit is an"inch", we would say 1inch  on the "map" is 200000inches on the "ground"
