sadie and nikhil are racing toy cars on several parallel line straight lined-tracks that start from a wall.

car a is places on the front track. the function a defined by a (x) = 30x+10 models the distance from the wall, in centimeters (cm) of car a in terms of the time x, in seconds, after the car was placed.

car b is placed on the second track. the table gives the distance from the wall, in cm, of car b for the first few second after the car was placed on the track. assume car b is travelling at a constant speed.

(question 1)

in this context, what is the best interpretation of the number 10 in the function a(x) = 30x +10?

a. the speed, in centimeters per second of car a 30 seconds after he car is placed on the track

b. the distance, in centimeters, car a is from the wall 30 seconds after the car is placed on the track

c. the speed, in centimeters per second, of car a at the moment the car is placed on the track

d. the distance, in centimeters, car a is from the wall at the moment the car is placed on the track.

(question 2) how many seconds after being placed on the track will car b reach a point 105 cm on the wall?

a. 4

b.6

c.8

d.12

(final question)

car c was placed on its track at the same time as car a. the table shows the distance from the wall, in cm, of car c for the first few seconds at it was placed on the track. if car c is traveling at a constant speed, after how many seconds will car c be the same distance from the wall as car a?

a. 0.5

b. 1

c. 10

d. 20
