If ten rows are each 1/4 mile long, what is the total length to treat in feet?

If ten rows are each 1/4 mile long, what is the total length to treat in feet?

• A. 6,600 feet
• B. 13,200 feet
• C. 21,600 feet
• D. 26,400 feet

Answer: (B)

Total length to treat comes from multiplying the number of rows by the length of each row: 10 rows × 1/4 mile per row equals 2.5 miles. Then convert miles to feet since the question asks for feet. There are 5,280 feet in a mile, so 2.5 miles × 5,280 feet per mile = 13,200 feet. Therefore the total length to treat is 13,200 feet, which matches the given option. The other numbers correspond to different totals (for example, 6,600 feet would be 1.25 miles, not the 2.5 miles in this problem).
