Sage travels around a go-cart track every 3 minutes. Marcus travels
around it every 4 minutes, and
Thomas travels around it every
6 minutes. They all start together.
How long will it be until they all
three get back to the start at the
same time?
A 6 minutes
B 12 minutes
C 18 minutes
D 24 minutes

B. 12 minutes

Step-by-step explanation:

3. 4. 6

6. 8. 12

12. 12

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
