Question

sean is a bookworm. on average, he reads 1 1/2 pages in 3 1/3 minute. Sean's average unit rate for reading is _ pages per minute.

Answer 1

Answer:  The required average unit rate for reading is $\dfrac{9}{20}$ pages per minute.

Step-by-step explanation:  Given that Sean is bookworm. On average, he reads $1\dfrac{1}{2}$ pages in $3\dfrac{1}{3}$ minute.

We are to find the average unit rate for reading the book.

We have

$1\dfrac{1}{2}=\dfrac{3}{2},~~~3\dfrac{1}{3}=\dfrac{10}{3}.$

We will be using the UNITARY method to solve the problem.

We have

Number of pages read in $\dfrac{10}{3}$ minutes is

$\dfrac{3}{2}.$

Therefore, the number of pages read in 1 minute is given by

$\dfrac{\frac{3}{2}}{\frac{10}{3}}\\\\\\=\dfrac{3}{2}\times\dfrac{3}{10}\\\\\\=\dfrac{9}{20}.$

Thus, the required average unit rate for reading is $\dfrac{9}{20}$ pages per minute.

Answer 2

Average = number of pages / time taken
             =  1. 1/2 / 3 1/3
              = 3/2  /   10/3
              = 3/2 * 3 /10
               = 9/20

Answer 9/20 pages per minute.
