Question

Three boards are placed end to end to make a walkway. The first board is 2 feet 9 inches long, the second board is 6 feet 11 inches long, and the third board is 6 feet 8 inches long. How long is the walkway? Write your answer in feet and inches. Use a number less than 12 for inches.

Answer 1

the answer is 16 feet 4 inches

Explanation:

2 ft + 6 ft + 6 ft = 14 ft
9 in + 11 in + 8 in = 28 in

28 in ÷ 12 in = 2 ft 4 in

14 ft + 2 ft 4 in = 16 ft 4 in
