To calculate the average time for the toy car to move 1.0 m on tile, we need to find the average of the three trial times on the tile surface:
- Trial 1: 29.1 s
- Trial 2: 26.7 s
- Trial 3: 28.5 s
To find the average, we add the times together and then divide by the number of trials:
\[ \text{Average time} = \frac{29.1 + 26.7 + 28.5}{3} \]
Calculating the sum:
\[ 29.1 + 26.7 + 28.5 = 84.3 , \text{s} \]
Now divide by the number of trials (3):
\[ \text{Average time} = \frac{84.3}{3} = 28.1 , \text{s} \]
Thus, the average time for the toy car to move 1.0 m on tile is 28.1 s.
