From Part 1
FINDING THE ACTUAL DISTANCE
TOPIC CODE: SCL421ARTC


 

To find actual Distance we use two methods:

(1) If given scale is statement scale, take the map distance multiply by given ground distance in the scale provided:

Example: if the scale is 1cm to 4km, take

MAP DITANCE X 4Km

if the scale is 1cm to 0.5km, take

MAP DITANCE X 0.5Km

 

2) If given scale is RF scale, put denominator of the scale over 100000 then multiply by Map distance provided.

Example: if the scale is 1:50000, take

MAP DITANCE X ⁵⁰⁰⁰⁰/₁₀₀₀₀₀

if the scale is 1:200000, take

MAP DITANCE X ²⁰⁰⁰⁰⁰/₁₀₀₀₀₀

Qu #5:

The map distance from one point to another is 5 cm, find the actual distance if the map scale is 1:50000

Solution

MAP DITANCE  X   ⁵⁰⁰⁰⁰/₁₀₀₀₀₀

5 cm   X  ⁵⁰⁰⁰⁰/₁₀₀₀₀₀     = 5cm  X  ¹/₂

Therefore the actual distance is 2.5 km

Qu #6:

The distance from home to school on a map drawn to a scale of 1cm to 3km is 10cm, find the actual distance from home to school

Solution

MAP DITANCE X 3Km = 10 X 3 = 30km

Therefore the actual distance is 30km
