The number of pages Cameron reads varies directly with time in minutes. He can read 15 pages in 60 minutes. What is the constant of proportionality for the number of minutes to read 1 page.
A. 4
B. - 1/2
C. - 1/4
D. 2
If the number of pages Cameron reads varies directly with time in minutes, then the ratio of pages to time should be constant.
Let's denote the constant of proportionality as k. We have the equation:
number of pages = k * time in minutes
We are given that Cameron can read 15 pages in 60 minutes. Using this information, we can set up the following equation:
15 = k * 60
Dividing both sides by 60, we find:
15/60 = k
Simplifying the left side, we have:
1/4 = k
Therefore, the constant of proportionality for the number of minutes to read 1 page is 1/4.
Answer: C. - 1/4
That was wrong
I apologize for the mistake. Let's try to solve the problem again.
We are given that the number of pages Cameron reads varies directly with time in minutes. This can be represented by the equation:
number of pages = constant of proportionality * time in minutes
Let's denote the constant of proportionality as k. We are told that Cameron can read 15 pages in 60 minutes. Using this information, we can set up the following equation:
15 = k * 60
To solve for k, let's divide both sides of the equation by 60:
15/60 = k
Simplifying the left side, we have:
1/4 = k
Therefore, the constant of proportionality for the number of minutes to read 1 page is 1/4.
Answer: C. 1/4
