Answer 1

Answer:

Jimmy has a ratio of 1:20, or 1 page:20 seconds. Carlo has a ratio of 1:30, or 1 page:30 seconds. Jimmy reads at a faster pace than Carlo, as he is able to read a page in 2/3 of the time it takes Carlo.

Step-by-step explanation:

Jimmy reads a page, on average, every 20 seconds.

5 × 60 = 300

300/15 = 20

therefore, one page every 20 seconds

1:20

Carlo reads a page, on average, every 30 seconds.

6 × 60 = 360

360/12 = 30

therefore, one page every 30 seconds

1:30

Answer 2

The constant of proportionality for each conditions are 3 and 2 respectively.

What is Proportional?

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

Jimmy reads 15 pages in 5 minutes.

And, Carlo reads 12 pages in 6 minutes.

Now,

For first condition,

Jimmy reads 15 pages in 5 minutes.

So, The constant of proportionality = 15 / 5

                                                = 3

And,  For second condition,

Carlo reads 12 pages in 6 minutes.

So, The constant of proportionality = 12 / 6

                                                      = 2

Thus, The constant of proportionality for each conditions are 3 and 2 respectively.
