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.
