Rather than remembering a list of the distances, you can calculate them instead using this method. It works for calculating the distances in feet. For example going 20mph has a factor of 2. Multiply the speed by the factor (2) to get 40 feet on a dry surface. Each increase in speed by 10mph increases the factor by 0.5.
So if you are traveling at 60mph, the factor is 4.5 giving a stopping distance of 315 feet.

If a car is traveling at a speed of 30 mph, it would take approximately 44 feet to come to a complete stop. This is calculated based on the average reaction time of 1.5 seconds and an average braking distance of around 110 feet at this speed.
Depends on the coefficient of friction between the wheel and the road, the mass of the car and the interference of any external forces whatsoever.
