Stopping distance at 30mph = 23m
about 22 metres
The answer will depend on the condition of the brakes and tyres. It will also depend on whether or not the road is dry and and on the amount of load being carried.
The overall stopping distance would be around 122m (400ft) This is made up of a thinking distance of 24m (79ft) and an actual stopping distance of 98m (321ft). The thinking distance is around 3m for every 10mph of speed and the overall stopping distance is calculated as follows: 2x20 ft at 20mph 2.5x30 ft at 30mph 3x40 ft at 40mph 3.5x50 ft at 50mph 4x60 ft at 60mph 4.5x70 at 70mph 5x80 at 80mph = 400 ft james s
At 20 mph, the average thinking distance is around 20 feet, while the braking distance is approximately 20 feet as well. Therefore, the overall stopping distance for a vehicle traveling at 20 mph would be around 40 feet.
120ft.I discovered a formula for calculating it for any given speed. I've tested it for 20mph, 30mph,40mph,50mph,60mph and 70mph. The formula is as follows:overall stopping distance in ft = Sp x (1 + Sp/20).Where Sp is the magnitude of the speed in mph.So at 40mph it is:40 x (1 + 40/20) = 50 x (1 + 2) = 40 x 3 = 120ft.
At 60mph, it generally takes longer to stop compared to 30mph due to the higher speed and momentum. Factors such as reaction time, braking distance, and road conditions also affect stopping time. In general, stopping at 60mph will take more than twice the distance compared to stopping at 30mph.
you're a tool. dependant upon inertia, stopping surface, braking potential, weight. lots of factors. a car may have ABS or not. this affects the final distance
Stopping Distance = 15 feet
Stopping Sight Distance
The answer cannot be calculated without further information. It would depend on your stopping power (brake system), the size/weight of the vehicle, etc.
they wer from 10mph to 30mph
