Response: Jimmy: He reads 15 pages in 5 minutes. the constant of proportionality is exactly: 15 pages/ 5 minutes which equals 3 pages per minute. and for Carlo: he reads 12 pages in 6 minutes. The constant of proportionality is 12 pages/ 6 minutes, which is 2 pages per minute. which means that Jimmy reads faster at 3 pages per minute, meanwhile Carlo reads way slower at 2 pages per minute.

Answer 1

Here’s a rephrased version of your response:

Jimmy is able to read 15 pages in 5 minutes. To find the constant of proportionality, we divide the number of pages by the time taken: 15 pages divided by 5 minutes equals 3 pages per minute. On the other hand, Carlo reads 12 pages in 6 minutes. Using the same method, we find that his constant of proportionality is 12 pages divided by 6 minutes, which gives us 2 pages per minute. This indicates that Jimmy has a faster reading speed of 3 pages per minute, while Carlo reads at a slower pace of 2 pages per minute.
