Chapter 5.2, Problem 46STP

To determine

To find: The fastest student.

Answer to Problem 46STP

The correct choice is (H).

Explanation of Solution

Given:

The given table is as follows.

Student	Folding Speed
Neiva	1 page every 3 seconds
Sarah	2 pages every 10 seconds
Quinn	30 pages per minute
Deron	45 pages in 2 minute

Calculation:

Divide the number of seconds by number of pages to get which student is fastest.

For Neiva it is 1 page every 3 seconds.

For Sarah,

  $\begin{array}{c}\frac{10}{2}=5\\ =\text{1}\text{page}\text{every}\text{5}\text{seconds}\end{array}$

For Quinn,

  $\begin{array}{c}\frac{60}{30}=2\\ =\text{1}\text{page}\text{every}\text{2}\text{seconds}\end{array}$

For Deron,

  $\begin{array}{c}\frac{120}{45}\approx 2.67\\ =\text{1}\text{page}\text{every}\text{2}\text{.67}\text{seconds}\end{array}$

So, $2<2.67<3<5$ which means Quinn is the fastest.

Therefore, the correct choice is (H).
