22 hours. A Silas ran 100 m race at a speed of 8 m/s. How long did it take him to com-
plete the race?​

100/8 = 12.5 (s)

Step-by-step explanation:

hmm bro

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
