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.
