Suppose that katie finished the race 0.13 second before Amy. what was katie's time in the race

katie's time would be _.47

Step-by-step explanation:

this answer varies because hypothetically katie could be 4.47 or 5.47

as long as you have the .47 because that would be 60-13=47 there are 60 seconds in a minute

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
