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.

So:

1 mile = 1760 yards = 1760 x 3 feet = 1760 x 3 x 12 inches = 63,360 inches in a mile.

And:

There are approximately 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 actually either 52,177 or 52,178 Sundays in a thousand years.

Hint
Try removing the spaces between the numbers.

Answer
48 and 11.

Reasoning
These are the squares of numbers without the correct spacing.

   1 4 9 16 25 36 49 64 81 100

with no spaces becomes:

   149162536496481100

broken into blocks of two:

   14 91 62 53 64 96 48 11 00

So the next two in the sequence are 48 and 11.
