Question
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.(2 points)

1 answer

To find the constant of proportionality for Jimmy, we divide 15 pages by 5 minutes:
15 pages ÷ 5 minutes = 3 pages per minute

To find the constant of proportionality for Carlo, we divide 12 pages by 6 minutes:
12 pages ÷ 6 minutes = 2 pages per minute

So, the constant of proportionality for Jimmy is 3 pages per minute and for Carlo is 2 pages per minute.

The proportional relationship can be compared by saying that Jimmy reads 1.5 times as fast as Carlo.
