Problems 14, 15 and 16 involve Mrs. Reed's English assignment.

A Novel Assignment

The students in Mrs. Reed's English class are reading the same 760-page novel. Three friends, Alice, Bob and Chandra, are in the class. Alice reads a page in 20 seconds, Bob reads a page in 45 seconds and Chandra reads a page in 30 seconds.

If Bob and Chandra both read the whole book, Bob will spend how many more seconds reading than Chandra?

$ \textbf{(A)}\ 7,600 \qquad 
\textbf{(B)}\ 11,400 \qquad 
\textbf{(C)}\ 12,500 \qquad 
\textbf{(D)}\ 15,200 \qquad 
\textbf{(E)}\ 22,800$
1. Determine the total time Bob spends reading the book:
   - Bob reads a page in 45 seconds.
   - The book has 760 pages.
   - Total time for Bob to read the book:
     \[
     760 \text{ pages} \times 45 \text{ seconds/page} = 34200 \text{ seconds}
     \]

2. Determine the total time Chandra spends reading the book:
   - Chandra reads a page in 30 seconds.
   - The book has 760 pages.
   - Total time for Chandra to read the book:
     \[
     760 \text{ pages} \times 30 \text{ seconds/page} = 22800 \text{ seconds}
     \]

3. Calculate the difference in time between Bob and Chandra:
   - Difference in time:
     \[
     34200 \text{ seconds} - 22800 \text{ seconds} = 11400 \text{ seconds}
     \]

Conclusion:
\[
\boxed{11400}
\]
