Question

What will be the ground distance if the map distance on a 1:50,000 scale map is measured as 5 cm?

• A. \(\text{0.5 km} \)
• B. \(\text{2.5 km} \)
• C. \(\text{50 m} \)
• D. \(\text{25 m} \)

Hint:

For scale calculations, multiply the measured distance on the map by the scale factor to obtain the actual ground distance.

Answer 1

The Correct Option is B

Step 1: Understanding scale calculations.  \(\text{Ground Distance} =\) \(\text{Map Distance}  \times \text{Scale Factor}\)

Given: - Map scale = 1:50,000 - Measured map distance = 5 cm 
Step 2: Calculating ground distance. \( \text{Ground Distance} \) = \(5 \times 50,000\)= 250,000 \(\text{ cm} \)  = 2500 \(\text{ m} \) = 2.5 \(\text{ km} \)  
Step 3: Selecting the correct option. Since the computed ground distance is 2.5 km, the correct answer is b. 2.5 km.
