Unless otherwise indicated it is 70 mph
70mph
It depends on the average speed which, in turn, depends on what the car is capable of, the speed limit(s), road conditions, traffic, stoppages. At 20 mph, the speed limit on my road, it would take 33.5 days! On a UK motorway, staying within the legal speed limit, just over 9.5 hours.
It depends on the speed that you drive at which, in turn, depends on the speed limit, road conditios, your vehicle, traffic etc. At 20 mph (the speed limit on my street) 5 hours. On a UK motorway, 1.43 hours or just over 1 hour 25 minutes. On roads without speed limit, less than that.
This question makes no sense, what do you mean? the speed of the car does not dictate the posted speed limit.
In a 20 mph speed zone 24 minutes. On a UK motorway (speed limit 70 mph) less than 7 minutes. On some European roads less than 5 minutes.
Whatever the posted speed limit is.
a car traveling the speed limit
The average speed of any car should be the posted speed limit.
It means the absolut limit to go on a car
Changing the speed limit should be considered based on factors like road conditions, traffic flow, and safety data. Conducting a thorough evaluation and consulting with traffic engineers and local authorities can help determine if a change is necessary to improve safety and efficiency on the road.
The speed limit is exactly that. The LIMIT. Driving faster than the limit can get you a ticket. So, No.
No. You're still bound by the speed limit.
