A car travels at the same speed in three different situations. The table shows the thinking distance and braking distance in each situation.
Table
| Situation | Thinking distance (m\text{m}m) | Braking distance (m\text{m}m) |
|---|---|---|
| Alert driver, dry road | 12 | 24 |
| Distracted driver, dry road | 20 | 24 |
| Alert driver, wet road | 12 | 36 |
Predict the stopping distance for a distracted driver on a wet road at the same speed.
