Hint
There are 1,760 yards in a mile, 3 feet in a yard, and 12 inches in a foot.
Answer
Inches in a mile.
Reasoning
There are 1,760 yards in a mile, 3 feet in a yard, and 12 inches in a foot.
There are 1760 x 3 x 12 = 63,360 inches in a mile, and around 1,000 x 52 = 52,000 Sundays in a thousand years.
Depending on the day of the week the first day of the year falls, there are either 52,177 or 52,178 Sundays in a thousand years.
