Alejandro read 4 pages in a book in 6 minutes. how long would you expect him to take to read 6 pages at this rate

9 minutes

Step-by-step explanation:

To find how long it would take to read 6 pages, find the unit rate or the time to read 1 page.

Alejandro read 4 pages in 6 minutes. This means it takes him 6/4 = 1.5 minutes to read 1 page.

To read 6 pages it will take him 6*1.5 = 9 minutes.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
