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

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.

Answer 2

Answer: The required average unit rate for reading is
`(9)/(20)` pages per minute.

Step-by-step explanation: Given that Sean is bookworm. On average, he reads
`1(1)/(2)` pages in
`3(1)/(3)` minute.

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

We have

`1(1)/(2)=(3)/(2),~~~3(1)/(3)=(10)/(3).`

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

We have

Number of pages read in
`(10)/(3)` minutes is

`(3)/(2).`

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

`((3)/(2))/((10)/(3))\\\\\\=(3)/(2)*(3)/(10)\\\\\\=(9)/(20).`

Thus, the required average unit rate for reading is
`(9)/(20)` pages per minute.
