PLZ Three toy cars race down a straight path. The distance each car traveled in meters, over time measured in seconds, is shown in the graph below.

1. At what speed is each car traveling? Where can you see each speed in the graph?

2. Explain the significance of the coordinate point (1,r),What do you think the “r” represent?

look a the sides they are perpendicular

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

the answer is 13 cm
