Rocky finished a 200-meter race in 5/12 of a minute. the winner finished 21/25 of rocks time to finish the race. how much time did the winner use to finish the race

Answer the winner finished the race in 1.75 minutes

Step-by-step explanation:

Rocky finished a 200-meter race in 5/12 of a minute.

The winner finished 21/25 of Rocks time to finish the race. This means that the time that the winner took in finishing the race would be

5/12 × 21/5 = 21/12 of a minute.

Converting to decimal, it becomes

1.75 minutes

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
