Answer:
D. 0.5 ft
Explanation:
Using the scale :
1 : 4000
This means that an altitude of 4000 feets is represented by 1 unit in the model.
Hence,
1 feet in model = 4000 feet actual altitude
Given an actual altitude of 2000 feets above ground level ;
Feets in the model will be x
1 feet = 4000 feet
x = 2000 feet
Cross multiply :
4000x = 2000
Divide both side by 4000
4000x / 4000 = 2000/4000
x = 0.5
Hence, 2000 feets above ground level corresponds to 0.5 feets in model
