Question

Ebecca reads a book at a rate of 1 page every 4 minutes. If her reading rate remains the same, which method could be used to determine the number of minutes for her to read 16 pages. Group of answer choices add 4 and 16 divide 16 by 4 multiply 4 by 16 subtract 4 from 16.

Answer 1

Multiply 4 by 16

Step-by-step explanation:

Given

`Rate = 1\ page/4\ minutes`

Required

Select the method that maintains her rate for 16 pages

To get the method for 16 pages, we simply multiply 4 by 16. This is shown below

`Rate = 1\ page/4\ minutes`

Calculate the unit rate

`Rate = (1)/(4) page/min`

`Rate = 0.25 page/min`

For 16 pages, it is:

`Rate = (16 page)/(4 min * 4)`

`Rate = (16 page)/(4 min * 16)` -- Here, we multiply 4 by 16

`Rate = (16 page)/(64\ min)`

`Rate = (16)/(64) page/min`

`Rate = 0.25 page/min`

See that the unit rates remain the same.

Other options will give different rates
