According to The Highway Code, total stopping distance consists of thinking distance plus braking distance. When driving a car at a speed of $20\text{ mph}$ ( $32\text{ km/h}$ ) on a dry road with good tyre and brake conditions, what is the total stopping distance in metres?

Cevap: 12 metres

Cevap

The total stopping distance is 12 metres.

Under normal, dry conditions as specified in The Highway Code, a car travelling at

20\text{ mph}

(

32\text{ km/h}

) has a thinking distance of

6\text{ metres}

(

20\text{ feet}

) and a braking distance of

6\text{ metres}

(

20\text{ feet}

). Adding these two values together gives a total stopping distance of

12\text{ metres}

(

40\text{ feet}

Adım Adım Çözüm

Determine the thinking distance at 20 mph

Thinking distance = 6 metres (20 feet)

The Highway Code defines thinking distance at 20 mph under normal conditions as 6 metres.

Determine the braking distance at 20 mph

Braking distance = 6 metres (20 feet)

The Highway Code defines braking distance on a dry road at 20 mph as 6 metres.

Calculate the total stopping distance by adding thinking distance and braking distance

6 metres + 6 metres = 12 metres (40 feet)

Total stopping distance is always the sum of thinking distance and braking distance.
