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 sentence to compare the proportional relationships.

Answer 1

To find the constant of proportionality for Jimmy, we divide the number of pages he reads by the amount of time it takes him. 15 pages / 5 minutes = 3 pages/minute.

To find the constant of proportionality for Carlo, we divide the number of pages he reads by the amount of time it takes him. 12 pages / 6 minutes = 2 pages/minute.

The proportional relationship for Jimmy is 3 pages per minute and for Carlo is 2 pages per minute.

Comparing the proportional relationships, we can see that Jimmy reads more pages per minute than Carlo.
