Answer: Hello there!
we know that sean reads on average (1 + 1/2) pages in (3 +1/3) minutes, and we want to know Sean's average unit rate: this is, the amount of time needed to read one page.
then we have:
(1 + 1/2) pages per (3 +1/3) minutes
solving the parentheses:
(3/2) pages per (10/3) minutes
dividing both sides bi (3/2)
1 page per (10/3)*(2/3) minutes = 20/9 minutes = (2/9 + 18/9) minutes = (2 + 2/9) minutes
then Sean needs on average (2 + 2/9) minutes to read one page.
