Near Daarle you are driving 130 km/h on a road without a speed limit. What is your reaction distance per the book's rule of thumb?
- ✓ 35.75 m
- 1 second
- 84.50 m
Correct answer: 35.75 m
Explanation
False
Why learners get this wrong
- '1 second' is the reaction second (time); the reaction distance is ((130:2)+10%):2 = 35.75 m
- 84.50 m is the braking distance (quadratic formula); the reaction distance uses a different, linear rule of thumb: ((130:2)+10%):2 = 35.75 m
