Jimmy reads 15 pages in 5 minutes. Carlo reads 12 pages in 6 minutes. Find each constant of proportionality, showing your work. Then write a sentence to compare the proportional relationships.

Answer 1

To find the constant of proportionality, we divide the number of pages read by the amount of time it takes.

For Jimmy, the constant of proportionality is 15 pages / 5 minutes = <<15/5=3>>3 pages per minute.

For Carlo, the constant of proportionality is 12 pages / 6 minutes = <<12/6=2>>2 pages per minute.

To compare the proportional relationships, we can say that for every minute Jimmy reads 3 pages, while Carlo reads 2 pages.
