Zorluk: KolayStopping and Following Distances

According to the UK Highway Code, the typical total stopping distance for a car travelling at 20 mph20\text{ mph} in good, dry conditions is 12 metres12\text{ metres} (40 feet40\text{ feet}).

Cevap: Cevap

Cevap

True
The statement is true because the UK Highway Code establishes that at 20 mph20\text{ mph}, thinking distance is 6 metres6\text{ metres} (20 feet20\text{ feet}) and braking distance is 6 metres6\text{ metres} (20 feet20\text{ feet}), giving a combined overall stopping distance of 12 metres12\text{ metres} (40 feet40\text{ feet}).

Adım Adım Çözüm

1
Identify the thinking distance and braking distance at 20 mph20\text{ mph} in dry conditions according to the UK Highway Code.
Thinking distance is 6 metres6\text{ metres} (20 feet20\text{ feet}) and braking distance is 6 metres6\text{ metres} (20 feet20\text{ feet}).
Overall stopping distance is always the sum of thinking distance and braking distance.
2
Calculate the total stopping distance by adding thinking and braking distances together.
6 m+6 m=12 metres6\text{ m} + 6\text{ m} = 12\text{ metres} (20 ft+20 ft=40 feet20\text{ ft} + 20\text{ ft} = 40\text{ feet}).
Confirming the total stopping distance confirms whether the given statement is true.
