To find the constant of proportionality for Jimmy, we divide the number of pages he reads by the time it takes him: 15 pages / 5 minutes = 3 pages per minute.
To find the constant of proportionality for Carlo, we divide the number of pages he reads by the time it takes him: 12 pages / 6 minutes = 2 pages per minute.
Therefore, the constant of proportionality for Jimmy is 3 pages per minute, and for Carlo it is 2 pages per minute.
In comparing the proportional relationships, we can see that for every 1 minute of reading, Jimmy reads 3 pages while Carlo reads 2 pages. Jimmy reads more pages per minute than Carlo, showing that Jimmy is a faster reader.
