If three friends continue to read every day at their rates, who will finish reading her book first? Second? Third?
This is a 7th-grade math sample item from the Partnership for Assessment of Readiness for College and Careers (PARCC), one of the two multi-state consortia developing Common Core tests.
On Friday, three friends shared how much they read during the week.
Barbara read the first 100 pages from a 320-page book in the last 4 days.
Colleen read the first 54 pages from a 260-page book in the last 3 days.
Nancy read the first 160 pages from a 480-page book in the last 5 days.
Part A: A person’s average reading rate can be defined as the number of pages read divided by the number of days. Place the three friends’ reading rates in order from greatest to least.
Part B: If the three friends continue to read everyday at their rates, who will finish reading her book first? Second? Third?
