The answer is between A and C.
Answer:
The correct answer would be - 1/2 ft.
Explanation:
if the scale is 1:4,000
It shows that the model plane will fly 1ft above the ground., the original plane flyes 4,000ft above the ground,
Now, if the plane flies 2,000ft above the ground, this is half times as the scale given, then the model plane will also fly half times as the number from the scale.
1/2*1ft = 1/2ft.
Now, we also can do it as:
4000 ft equivalent to 1 ft.
2000ft equivalent to x
x = 1ft*(2000ft/4000ft) = 1ft*1/2 = 1/2ft.
