Zorluk: KolayStopping Distances

According to the official UK Highway Code, total stopping distance depends directly on vehicle speed under good, dry road conditions. Match each vehicle speed on the left to its corresponding typical overall stopping distance on the right:

  • 20 mph20\text{ mph}12 metres (40 feet)12\text{ metres } (40\text{ feet})
  • 50 mph50\text{ mph}53 metres (175 feet)53\text{ metres } (175\text{ feet})
  • 60 mph60\text{ mph}73 metres (240 feet)73\text{ metres } (240\text{ feet})
  • 70 mph70\text{ mph}96 metres (315 feet)96\text{ metres } (315\text{ feet})

Cevap

20 mph20\text{ mph} matches 12 metres (40 feet)12\text{ metres } (40\text{ feet}), 50 mph50\text{ mph} matches 53 metres (175 feet)53\text{ metres } (175\text{ feet}), 60 mph60\text{ mph} matches 73 metres (240 feet)73\text{ metres } (240\text{ feet}), and 70 mph70\text{ mph} matches 96 metres (315 feet)96\text{ metres } (315\text{ feet}).
According to The Highway Code table for standard stopping distances on dry roads: 20 mph20\text{ mph} requires 12 metres (40 feet)12\text{ metres } (40\text{ feet}); 50 mph50\text{ mph} requires 53 metres (175 feet)53\text{ metres } (175\text{ feet}); 60 mph60\text{ mph} requires 73 metres (240 feet)73\text{ metres } (240\text{ feet}); and 70 mph70\text{ mph} requires 96 metres (315 feet)96\text{ metres } (315\text{ feet}).

Adım Adım Çözüm

1
Recall the fundamental stopping distance formula
Total Stopping Distance = Thinking Distance + Braking Distance
The Highway Code defines total stopping distance as the sum of reaction/thinking distance and vehicle braking distance.
2
Identify the standard dry-road stopping distances for each speed given in The Highway Code
20 mph = 12 m (40 ft); 50 mph = 53 m (175 ft); 60 mph = 73 m (240 ft); 70 mph = 96 m (315 ft)
These are the official baseline values tested in UK driving theory assessments.
3
Link each vehicle speed to its exact total stopping distance
Each speed is matched with its correct measurement pair.
Fulfills the matching requirement.
