Stopping Distance = about 75 feet.
When traveling 30-mph, the braking distance is 45-feet, and the total stopping distance is 75-feet. This is the length of a semi-truck and trailer.
23 meters on a dry pavement.
Stopping Distance = about 315 feet at 70 mph
Stopping Distance = 15 feet
23 meters in normal conditions
The total stopping distance for a car travelling at 30 mph on a dry surface is about 75 feet. However, you may wish to note that in most countries, driving a car on the pavement is illegal.
Stopping Distance = about 146.25 feet.
Stopping distance at 40mph = 36m
The faster you are going the longer the stopping distance is. The slower you are going the shorter the stopping distance is. E.G. Speed of a car Thinking distace Breaking distance Total stopping distance mph meters meters meters 30 9 14 23 40 12 24 36 50 15 38 53 70 21 75 96
Need car's weight and stopping power to compute.
Most cars can stop from 60 mph in about 100 feet or so. If the relationship is linear then a car should stop from 30 mph in about 50 feet.
You should not be travelling on a pavement at 70 mph!
using the formula, speed squared divided by 20 plus speed gives 40 feet approximate stopping distance at 20mph.
Stopping Distance = about 206.25 feet at 55 mph
The typical BREAKING distance from 50mph is 38meters, but the overall stopping distance is 53meters (overall stopping distance is made up of thinking distance, which is 15meters in this case, + breaking distance)
That depends on what vehicle you are stopping from 55 mph. the laws of physics come into play. The heavier the vehicle the longer the stopping distance. So I cannot give an accurate answer except to say that from 60 mph the average for a mid-sized car is around 135 feet.
53 metres/ 175 feet
Any regular passenger vehicle traveling at a speed of 20 mph should stop within a distance of 25 feet, once the brake is applied. At 35 mph, the distance will be approximately 106 feet. At 55 mph, it will be approximately 228 feet. An increase speed will always result in longer stopping distances. In addition, factors such as road and weather conditions and traffic density also affect the vehicle's stopping distance. -Mary Mimms
