Sandra is conducting an experiment on the speed of toy cars and how they are affected by the type of surface they are placed on. Sandra measures the distance each car travels on carpet, tile and hardwood floors. She also records the time each toy car takes to cover the distance. Which of the following is the appropriate measuring instrument and unit for measuring distance in this experiment
A. yard stick; kilometer
B. ruler; centimeter
C. ruler; inches

I would think that the cars would go farther than 12 inches on hardwood or tile floors.
