What is the average time for the toy car to move 1.0 m on tile?

To determine the average time for the toy car to move 1.0 m on tile, we would need the actual time measurements for multiple trials of the toy car moving 1.0 m. With the individual time measurements, we can calculate the average time by summing up all the time values and dividing by the number of trials.
