To find the constant of proportionality, we can divide the number of pages by the number of minutes for each person.

Question

For Jimmy, the constant of proportionality is:

15 pages / 5 minutes = 3 pages per minute.

For Carlo, the constant of proportionality is:

12 pages / 6 minutes = 2 pages per minute.

To compare the proportional relationships, we can say that Jimmy reads at a faster rate than Carlo. For every minute, Jimmy reads 3 pages while Carlo reads 2 pages.

Answer 1

Therefore, Jimmy's constant of proportionality is 3 pages per minute and Carlo's constant of proportionality is 2 pages per minute.
