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.

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
