Using the 3-second rule, what is the minimum following distance in meters for a car travelling at 126 km/h?
Answer and explanation
Correct answer: B. 105 m
- Step 1: 126 km/h = 35 m/s.
- Step 2: Distance = 35 x 3 = 105 m.
Answer
105 m.
Why not the others: The gap is the distance covered in the chosen number of seconds; one second only, a rule of thumb in tens, or half the gap are not the two-second or three-second gaps.
