The car will move 13.60 m

#### Explanation:

We have distance

Before the driver reacts, the car will have moved

The time for the car to stop can be found from

The average speed during this time is

Therefore, the car moves

Total distance moved before the car stops, therefore, is

(5.831+7.772) m = 13.603 m

Rounded to 2 decimals: 13.60 m
