S = f/h.
S = (15÷100)/300,
S = 1:2000.
S = (15÷100)/300,
S = 1:2000.

The height should be 3000m.
Then 1:20,000 is correct.
Then 1:20,000 is correct.

Scale = f/(H-h).
H = height of camera.
h = height of ground.
h = 0.
Scale = 15/(300*100)=1:20000.
H = height of camera.
h = height of ground.
h = 0.
Scale = 15/(300*100)=1:20000.
