In the Highway Code, you learn about the factors that may increase stopping distance, this can be broken down into factors that have a direct impact on Thinking Distance (the time it takes for you to apply your brakes) and Braking Distance (the distance your car travels after you apply the brake). The upshot of the figures being quoted in your maths course is that the Highway Code gives a stopping distance from 70mph of 315 feet (about 20 Mondeos) in perfect conditions.With "good" tyres and brakes, and again in perfect conditions, you might be able to stop in 270 feet - or about 3 Mondeos less.
