A group of students investigated how the speed of a toy car affects its braking distance. Table 1 shows their results for one of the speeds tested.
Table 1
| Trial | Braking distance (cm) |
|---|---|
| 1 | 42.0 |
| 2 | 44.5 |
| 3 | 68.0 |
| 4 | 41.5 |
| 5 | 44.0 |
Use the results in Table 1 to calculate the mean braking distance.
