Julia has read her favorite book 6 times, this is 3 times more than her kami. how many times has kami read the book?

   The answer is:  " 2 " .  

        → Kami has read the book "  2 (two)  " times.

Step-by-step explanation:

Let "J" represent the number of times julia has read the book.

Let "K" represent the number of times Kami has read the book.

J = 6 ;  

J = 3K ;  

Solve for "K" ;

J = 6 = 3K ;

→ 6 = 3K ;

 ↔  3K = 6 ;

Divide each side of the equation by "3" ;

to isolate "K"  on one side of the equation; & to solve for "K" :

→  3K / 3  =  6 / 3 ;

to get:

  K = 2 .

 The answer is:  " 2 " .

        → Kami has read the book "  2 (two)  " times.

im not sure

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
