2. A car is moving along an open road. Suddenly, a sheep walks into the road.
· What do we call the distance the car travels before the driver puts their foot on the brakes?
o Thinking distance
· Name one factor that could increase the distance the car travels in this time.
o high speed of car, use of drugs or alcohol, medication, tiredness
· The braking distance is 35m for the car. If the stopping distance is 50m, how far did the car travel before the driver put their foot on the brakes?
o Stopping Distance = Braking distance + Thinking Distance
o 50m = 35m + Thinking Distance
