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 scentence to compare the proportional relationships.
To find the constant of proportionality for Jimmy, we divide the number of pages he reads (15) by the time it takes him to read those pages (5 minutes):
Constant of proportionality for Jimmy = 15 pages / 5 minutes = 3 pages per minute
To find the constant of proportionality for Carlo, we divide the number of pages he reads (12) by the time it takes him to read those pages (6 minutes):
Constant of proportionality for Carlo = 12 pages / 6 minutes = 2 pages per minute
Thus, the constant of proportionality for Jimmy is 3 pages per minute, and the constant of proportionality for Carlo is 2 pages per minute.
A sentence to compare the proportional relationships could be: Jimmy reads 3 pages per minute, while Carlo reads 2 pages per minute, showing that Jimmy reads at a faster rate than Carlo.
