How many feet will it take if a car is going 30 mph?

Answer 1

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.

Answer 2

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.
