How would I find the acceleration of a car if it traveled 1.5 meters in one second?

If it is accelerating at a constant rate with zero initial velocity, then use the formula
X = (1/2) a t^2 and solve for the acceleration, a.
X = 1.5 m, and t = 1 s.

It could be not accelerating at all, but just have a constant velocity of 1.5 m/s, which is pretty slow for a car. In this case a would be zero. You have not fully defined the problem.

well we had to do a lab in physics where we determine how fast we walk and how fast a model car goes. i walked one meter per second and the car went 1.5 meters per second. Now I need to calculate the acceleration of the car.

If the car started from rest, then use the method I mentioned.
