You might be in good condition but what about the road condition (wet, icy), the state of you tyres (good tread or worn), the state of your brakes?
Stopping distances are measured in feet not in seconds. At 40 mph you're traveling 58.7 feet per second. The average driver reaction time is about 3/4 second which equates to 44 feet. After applying the brakes it will take approximately 82 feet to stop the vehicle. The total stopping distance for a car traveling 40 mph will be 126 feet when you include reaction time and actual stopping distance of the vehicle. If you divide 126' x 58.7' which is the distance traveled per second you get 2.14 seconds. This is assuming you're paying attention and have average reaction time while driving.
40 mph = 40 miles in 60 minutes = 20 miles in 30 minutes.
Just divide the distance by the speed.
Distance = Rate * Time or, for our purpose Time = Distance/Rate at 50 mph Time = 4.5 miles/50 mph = 0.09 hours = 5.4 minutes ----------------------------- at 40 mph Time = 4.5 miles/40 mph = 0.1125 hours = 6.75 minutes ---------------------------------------------------- 6.75 - 5.4 = 1.35 minutes saved
The vehicle's reaction distance depends on the driver's reaction time.
44feet
Not enough information in your question. It will depend on multiple factors, like vehicle weight, vehicle condition, tire condition, road surfacing and type of road surfacing, driver reaction speed.

On average it is in the low 80ft range. Depends on the vehicle, yr/make/model.
It would depend on the vehicle.
Stopping distance at 40mph = 36m
40 mph = 40 miles in 60 minutes = 20 miles in 30 minutes.
Just divide the distance by the speed.
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.
