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.

Puzzle 154
As I was going to St Ives,
I met a man with seven wives.
Each wife had seven sacks,
Each sack had seven cats,
Each cat had seven kits.
Kits, cats, sacks and wives,
How many were going to St. Ives?
This is a very old puzzle, and appeared in a manuscript dated around 1730. It is thought to refer to a town in Cornwall, UK.
If we were to count everyone and everything, including all of the kits, cats, sacks and wives, we would have:
Me = 1
Man = 1
Wifes = 7
Sacks = 7 x 7 = 49
Cats = 7 x 7 x 7 = 343
Kits = 7 x 7 x 7 x 7 = 2401
