Kayden is a stunt driver. One time, during a gig where she escaped from a building about to explode(!), she drove
at a constant speed to get to the safe zone that was 160 meters away. After 3 seconds of driving, she was 85
meters away from the safe zone.
Let y represent the distance (in meters) from the safe zone after a seconds.
Which of the following could be the graph of the relationship?

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

Yea they are simplyfiy the ratios
