According to The Highway Code, total stopping distance is comprised of thinking distance and braking distance. On a dry, level road with good tyres and brakes, what is the typical braking distance for each vehicle speed? Match each vehicle speed to its corresponding braking distance.

Travelling at $30\text{ mph}$ ( $48\text{ km/h}$ ) $14\text{ metres}$ ( $45\text{ feet}$ )
Travelling at $40\text{ mph}$ ( $64\text{ km/h}$ ) $24\text{ metres}$ ( $80\text{ feet}$ )
Travelling at $50\text{ mph}$ ( $80\text{ km/h}$ ) $38\text{ metres}$ ( $125\text{ feet}$ )
Travelling at $70\text{ mph}$ ( $112\text{ km/h}$ ) $75\text{ metres}$ ( $245\text{ feet}$ )

Cevap

Travelling at 30 mph matches 14 metres (45 feet); Travelling at 40 mph matches 24 metres (80 feet); Travelling at 50 mph matches 38 metres (125 feet); Travelling at 70 mph matches 75 metres (245 feet).

Under The Highway Code standard dry road figures: at 30 mph, the braking distance is 14 metres (45 feet); at 40 mph, it is 24 metres (80 feet); at 50 mph, it is 38 metres (125 feet); and at 70 mph, it is 75 metres (245 feet).

Recall The Highway Code formula for overall stopping distances

Total Stopping Distance = Thinking Distance + Braking Distance

Understanding the separation of components is necessary to isolate braking distance from total distance.

Determine the braking distance for 30 mph and 40 mph

At 30 mph, braking distance is 14 metres (45 feet). At 40 mph, braking distance is 24 metres (80 feet).

Braking distance increases non-linearly with speed due to kinetic energy scaling with the square of velocity.

Determine the braking distance for 50 mph and 70 mph

At 50 mph, braking distance is 38 metres (125 feet). At 70 mph, braking distance is 75 metres (245 feet).

Applying the standard official Highway Code values for higher speeds under dry conditions.

Match each speed with its respective braking distance value

30 mph to 14 m (45 ft); 40 mph to 24 m (80 ft); 50 mph to 38 m (125 ft); 70 mph to 75 m (245 ft).

Completes the required pair-wise matching accurately.
