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 1/4
B 1/2
C 2
D 4
I think its d
the answer is d
To determine the constant of proportionality, we can use the formula for direct variation:
Direct Variation: y = kx
In this case, y represents the number of pages and x represents the time in minutes. We are given that Cameron can read 15 pages in 60 minutes. Therefore, we can substitute these values into the formula:
15 = k * 60
To find the value of k, we need to isolate it. Divide both sides of the equation by 60:
15/60 = k
Simplify the fraction:
1/4 = k
So, the constant of proportionality for the number of minutes to read 1 page is 1/4.
Therefore, the correct answer is A) 1/4.
p = kt
60 = k*15
so, what do you think?
