Question 8 of 20
In 1997, the Library of Congress held 17,402,100 books. If we assume that each book has 300 pages with 450 words per page, this totals about 135,000 words per book or 2.35 trillion words. If we further assume that each word averages about 7 letters, the information can be digitized using ASCII code, in which each letter represents 7 bits. Therefore, all of the holdings of the Library of Congress would amount to 115.11 trillion bits of information. How long it would take to transmit the entire collection of the Library of Congress using an optical fiber that has the transmission speed of 100 trillion bits per second?

A. 1.15 seconds
B. 11.5 seconds
C. 115.11 seconds
D. 1151.1 seconds
