On a provincial road near Wierden you are driving 100 km/h. What is your braking distance per the book formula?
- ✓ 50.00 m
- 100.00 m
- 200.00 m
Correct answer: 50.00 m
Explanation
False
Why learners get this wrong
- (10x10):2 = 50.00 m — don't forget the division by 2
- Braking distance is quadratic, not a doubling of some earlier figure: (10x10):2 = 50.00 m
