Answer: Photograph scale= 1:12500 Since the distance between two road intersections on aerial photograph is nearly twice that of topographic map, So the aerial photograph scale must be lower in comparison with topographic map. 47.2mm is almost half of 97.4mm that's why the aerial photograph scale must be 1 : (25000/2) = 1 : 12500 So, the photograph scale should be around 1 : 12500.
