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.(2 points

Answer 1

To find the constant of proportionality for Jimmy, divide the number of pages he reads (15) by the number of minutes it takes (5):
Constant of proportionality for Jimmy = 15/5 = 3 pages/minute

To find the constant of proportionality for Carlo, divide the number of pages he reads (12) by the number of minutes it takes (6):
Constant of proportionality for Carlo = 12/6 = 2 pages/minute

The constant of proportionality for Jimmy is 3 pages/minute and for Carlo is 2 pages/minute.

A comparison between the proportional relationships can be made by stating that Jimmy reads 1 extra page per minute compared to Carlo.
