Landon reads for 45 minutes 5 times a week. Marisa reads for 100 minutes 3 times a week. Daniel reads for 25 minutes 7 times a week. Out of the three students who reads the most per week? What is the difference between the person who reads the most and the person who reads the least?

Marisa

Step-by-step explanation:

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
