Your problem is missing information. However;
1.5:25 scale
25/1.5 = 16 2/3 miles per inch
For any map distance multiply the number of inches by 16 2/3 or 50/3
to get the real distance
1.5/25 = 0.06 inches per mile 0r 6/100 = 3/50
For any real land distance in miles, multiply by 0.06 or 3/50 to get the map distance in inches.
Note how these are reciprocals of each other. Since we are going the opposite direction
the mathematical processes are inverses.
