Stopping distance at 40mph = 36m
37 mts
85 feet
Stopping Distance = about 315 feet at 70 mph
using the formula, speed squared divided by 20 plus speed gives 40 feet approximate stopping distance at 20mph.
Stopping distance at 30mph = 23m
Stopping Distance = 15 feet
It depends on the car's stopping power. An average distance for 40 mph would be around 85 feet
Stopping Distance = about 146.25 feet.
Stopping Distance = about 75 feet.
When traveling 30-mph, the braking distance is 45-feet, and the total stopping distance is 75-feet. This is the length of a semi-truck and trailer.
The faster you are going the longer the stopping distance is. The slower you are going the shorter the stopping distance is. E.G. Speed of a car Thinking distace Breaking distance Total stopping distance mph meters meters meters 30 9 14 23 40 12 24 36 50 15 38 53 70 21 75 96
