The formula for the distance (in meters) that you will travel from the moment you hit the brakes until a full stop is: speed ./. 3 x 10. So at your speed that will be: 30 ./. 3 = 10 x 10 = 100 meters. Sounds like a lot, but if you brake as a reaction to a traffic situation ahead of you, you will travel on for a full second before you even hit the brakes, even if you're alert.
It only takes one, as long as it's the one on the brake pedal.
A average freight train going 50 mph (80 km/h) will take up to 1.5 miles. That is how long a freight train takes to stop if it collides with a car.
1 mile
It takes a car 387 feet to come to complete stop when going 70mph.
average car takes 1 average car length per 10 mph.
100 feet
It takes 7.999 minutes.
It depends on the condition of the brakes and the road.
If you drive non-stop at a constant speed of 65 mph, it takes about 1 hour and 24 minutes.
That's going to depend heavily on the weight of the cargo in each car.
At 10 mph it takes 2 hours! At 20 mph it takes a hour At 30 mph it takes 45 minutes At 40 mph it takes half a hour
It takes a minimum of 135 feet for a car to stop at 45 miles per hour. The wear of the tires makes a difference in the distance too.
