If 1 / 4 inch on the map represents 8 miles on real land, 1 inch represents 4 * 8 = 32 miles. Since 1 inch represents 32 miles, 3 inches represent 3 * 32 = 96 miles. 1 / 4 inch represents 8 miles, 1 / 8 inch represents 8 / 2 = 4 miles because 1 / 8 is half of 1 / 4. If 1 / 8 inch represents 4 miles, 3 / 8 of an inch represents 3 * 4 = 12 miles. This means 3 3 / 8 inches on the map translate to 96 + 12 = 108 miles.
The answer: 108
