Michael reads 12 pages of a book in 18 minutes,8 pages in 12 minutes and 20 pages in 30 minutes. is this a proportional relationship? if so, what is the constant of proportionality? write an equation. (i'm focusing on the equation)

y = 1.5x

Step-by-step explanation:

What you would do is divide all of the minutes by the amount of pages to find how long for each rate for one page. (ex. 18/12, michael reads 1 page in 1.5 minutes. 12/8, michael reads 1 page in 1.5 minutes. 30/20, michael reads one page in 1.5 minutes) Therefore, yes it is proportional, and the equation is y=1.5x (there is no y intercept)

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
