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.

Stopping distance of a car traveling at 80mph?
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
If a car traveling 40mph requires 150ft to stop find the stopping distance for a car traveling 80mph?
You can use a ratio here, say 40mph/150ft = 80mph/xft then cross multiply: 40x = 150 * 80 40x = 12000 x = 300
