To find the constant of proportionality for Jimmy's reading rate, we divide the number of pages he reads (15) by the amount of time it takes him to read (5). Therefore, the constant of proportionality for Jimmy is 15/5 = 3 pages per minute.
To find the constant of proportionality for Carlo's reading rate, we divide the number of pages he reads (12) by the amount of time it takes him to read (6). Therefore, the constant of proportionality for Carlo is 12/6 = 2 pages per minute.
The proportional relationship for Jimmy is 3 pages per minute and for Carlo is 2 pages per minute. Jimmy's reading rate is faster than Carlo's.
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 short sentence to compare the proportional relationships.
