Hint
There are 12 inches in a foot and 1,760 yards in a mile.
Answer
Feet in a 20-mile walk.
Reasoning
There are 12 inches in a foot, 3 feet in a yard, and 1,760 yards in a mile:
square inches in a piece of carpet 15 yards by 5 yards
(15 x 3 x 12) x (5 x 3 x 12) = 97,200 square inches.
feet in a 20-mile walk
20 x 1760 x 3 = 105,600 feet.
