To find the constant of proportionality, divide the number of pages by the time.
For Jimmy, the constant of proportionality is 15 pages / 5 minutes = 3 pages/minute.
For Carlo, the constant of proportionality is 12 pages / 6 minutes = 2 pages/minute.
To compare the proportional relationships, we can see that Jimmy reads 3 pages every minute, while Carlo reads 2 pages every minute. Thus, Jimmy reads more pages per minute than Carlo.
