92 billion light years.

Explanation:

Astronomers do not measure distance in miles, the number becomes too large too quickly. The light year is the standard measure. A light year is #6.2 xx 10^12# miles. #92# billion light years equates to #9.2 xx 10^9#. Multiply the two and you get #5.7 xx 10^22# miles.
