12 miles
Stopping distance at 40mph = 36m
its the trany going out.
Reaction distance is the distance a vehicle will travel before the operator can react to what is observed. This distance will vary depending on the speed of the vehicle. The reaction distance is actually the reaction time of the operator.
40mph is about 64.3km/h
Stopping Sight Distance
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.
40mph = 64.3738kmph
The vehicle's reaction distance depends on the driver's reaction time.
You can use a ratio here, say 40mph/150ft = 80mph/xft then cross multiply: 40x = 150 * 80 40x = 12000 x = 300
reaction distance is the distance travelled from the time you see and analyze a threat, to the time you actually physically react.
