Julissa is running a 10-kilometer race at a constant pace. After running for 18 minutes, she completes 2 kilometers. After running for 54 minutes, she completes 6 kilometers. Her trainer writes an equation letting t, the time in minutes, represent the independent variable and k, the number of kilometers, represent the dependent variable. Which equation can be used to represent k, the number of kilometers Julissa runs in t minutes? k – 2 = (t – 18) k – 18 = (t – 2) k – 2 = 9(t – 18) k – 18 = 9(t – 2)

    Okay so we know that two kilometers are equal to fifty-four minutes. So what were gonna do is take that fifty-four minutes and divide it by two. 54/2=? <----- Leave that to you. After that your answer should look like. ?=One kilometer. <----- Your job. So after this we will take. 6x?=? <----- Work. So now which one do you think it is?
