Among the listed minimum approach distances (3 ft, 8 ft, 15 ft, 6 inches), which is the largest?

• A. 3 ft.
• B. 8 ft.
• C. 15 ft.
• D. 6 inches.

Answer: (C)

When comparing different distances, first make the units consistent. Convert 6 inches to feet: 6 in = 0.5 ft. Now you have 0.5 ft, 3 ft, 8 ft, and 15 ft. The largest value is 15 ft, so that is the correct choice. The main idea is to normalize units before comparing numbers.
