One advantage of Binary Search Algorithm:
Compared to Linear search it is much faster because linear search starts its searching right from the first value but binary searches for something by splitting the array in two again and again and again.

You also learn in class that one kilobyte of computer memory will hold about 2/3 of a page of typical text (without formatting).

Answer:

The flashdrive can hold 35389 400-pages-books

Explanation:

If $\frac{2}{3}$ of a page occupies 1 kB of memory, we can calculate how much memory a book will take

$2/3kB=1 page\\ x kB=400 pages\\266.67 kB=400 pages$

Now that we know that a book average file size is about 266,67 kB, we calculate how many of them can a 9 GB flash drive hold.

To do the calculation, we have to know how many kilobytes are in 9 gigabytes.

There is 1024 kilobytes in a megabyte, and 1024 megabytes in a gigabyte, so:

$Memory_{in _kilobytes}^{} =1024\frac{kilobytes}{megabytes} *1024\frac{megabytes}{gigabytes}*9=9437184 kilobytes$

Finally, knowing the average file size of a book and how much memory in kilobytes the 9 GB flash drive holds, we calculate how many books can it hold.

$Books=\frac{Flash drive memory}{Filesize of a book} =\frac{9437184kilobytes}{266.67\frac{kilobytes}{book} } =35389,4 books$
