In the built-up area of Hellendoorn you explain to a passenger: 'If you accelerate from 50 km/h to 100 km/h, your braking distance becomes exactly 2x as long.'
- True
- ✓ False
Correct answer: False
Explanation
False
Why learners get this wrong
- Braking distance at 50 km/h = 12.50 m; at 100 km/h = 50.00 m — that is 4x, not 2x
