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

Answer:

Multiply 4 by 16

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

$Rate = \frac{1}{4} page/min$

$Rate = 0.25 page/min$

For 16 pages, it is:

$Rate = \frac{16 page}{4 min * 4}$

$Rate = \frac{16 page}{4 min * 16}$ -- Here, we multiply 4 by 16

$Rate = \frac{16 page}{64\ min}$

$Rate = \frac{16}{64} page/min$

$Rate = 0.25 page/min$

See that the unit rates remain the same.

Other options will give different rates
