Jimmy read 15 pages in 5 minutes. Carlo reads 12 pages in 6 minutes . Find each constant of proportionality, showing your work. Then write a sentence to compare the proportional relationship
To find the constant of proportionality for Jimmy, we can divide the number of pages he read (15) by the time it took him to read those pages (5 minutes):
Constant of proportionality for Jimmy = 15 pages / 5 minutes = 3 pages/minute
To find the constant of proportionality for Carlo, we can divide the number of pages he read (12) by the time it took him to read those pages (6 minutes):
Constant of proportionality for Carlo = 12 pages / 6 minutes = 2 pages/minute
So, the constant of proportionality for Jimmy is 3 pages/minute and for Carlo is 2 pages/minute.
To compare the proportional relationship, we can say that for every 1 minute, Jimmy reads 3 pages, while Carlo reads 2 pages. Jimmy reads faster than Carlo.
