What is the formula for stopping distance in a car?
Stopping distance = reaction distance + braking distance.
How do you calculate stopping distance and speed?
Stopping distance = thinking distance + braking distance
Thinking distance is approximately 1 foot for every mph you travel at, for example, a car travelling at 30mph will travel 30 feet before the brakes are applied.
What is the total stopping distance at a speed of 60 mph?
Driver Care – Know Your Stopping Distance
| Speed | Perception/Reaction Distance | Braking Distance |
|---|---|---|
| 50 mph | 73 feet | 125 feet |
| 60 mph | 88 feet | 180 feet |
| 70 mph | 103 feet | 245 feet |
| 80mph | 117 feet | 320 feet |
What’s the stopping distance at 40mph?

Stopping Distance: Is The Highway Code Wrong?
| Speed | Stopping Distance |
|---|---|
| 30mph | 23 Meters / 75 Feet |
| 40mph | 36 Meters / 118 Feet |
| 50mph | 53 Meters / 175 Feet |
| 60mph | 73 Meters / 240 Feet |
What is the stopping distance at 55 mph?
approximately 302 feet
Total stopping distance; traveling at 55 mph, it will take about 6 seconds to stop your vehicle. The vehicle will travel approximately 302 feet before coming to a stop. That is longer than the length of a football field.
When you double your speed from 20 to 40 mph your vehicle’s stopping distance is?
4 times
The faster you drive the longer it takes to stop. This means speeding increases your stopping distance and force of impact. Double your speed from 20 to 40 mph your braking distance and force of impact are 4 times greater. Triple your speed from 20 to 60 mph and your braking distance and impact are 9 times greater.
How long does it take a car to stop at 75 mph?
Therefore, if you are driving 75 mph, it will take you approximately 356.25 feet to stop your car.
How long does it take to stop at 70 mph?
Stopping distances at different speeds
| Speed | Thinking + braking distance | Stopping distance |
|---|---|---|
| 40mph | 12m + 24m | 36m (118 feet) |
| 50mph | 15m + 38m | 53m (174 feet) |
| 60mph | 18m + 55m | 73m (240 feet) |
| 70mph | 21m + 75m | 96m (315 feet) |
What is the safe stopping distance at 70 mph?
What is braking distance?
| Speed | Braking distance |
|---|---|
| 40mph | 24 metres |
| 50mph | 38 metres |
| 60mph | 55 metres |
| 70mph | 75 metres |
What is the stopping distance at 65 mph?

What is the braking distance at 50 mph?
At 50 mph, the typical thinking distance will be 15 metres (50 feet), plus a braking distance of 38 metres (125 feet), giving an overall stopping distance of 53 metres (175 feet). The stopping distance could be greater than this, depending on your attention and response to any hazards.
What is stopping distance at 40mph?
How long does it take a car to stop at 80mph?
In that 4.5 seconds, a distance of approximately 271 feet is covered. Based on this information, one might conclude that it would take approximately 6 seconds, or 360 feet, to stop a vehicle traveling at 80 mph. This would make sense based solely on the fact that 80 mph is one-third faster than 60 mph.
