252 feet or less on typical dry road in US.
The basic answer is based on US Department of Transportation minimum requirements, which requires that brakes, tires, suspension, result in a passenger car being slowed at a rate of 21 feet per second per second (21fps^2) or better. If we convert 70mph to feet per second (multiply 70 x 1.467) we get 103 feet per second. So the time it takes to stop will be 103/21, or 4.9 seconds. Using straight line deceleration this comes to 252 feet.
If everything is in good shape and typical dry road, it will take the brakes 252 feet to stop after brakes are applied. This doesn't include reaction time yet (0.4 seconds for an alert driver), as the car will travel 41 feet before he even hits the brakes. We add this to get total of 293 feet, if you include reaction time. Note that all US cars well exceed these limits, providing for a safety factor for wet roads, and other factors. You should find under ideal conditions the actual braking distance will be under 170 feet.
average car takes 1 average car length per 10 mph.
Nether what you should do is just take your foot off the gas and let it roll down the hill to its destination.My answer:When going downhill it may be necessary to slow down to maintain steering control. Using brakes only on a long steep decline can cause the brakes to heat up and fail. Any gasoline engine or a diesel engine equipped with a "Jake Brake" can provide additional braking without heating the brakes. With many automatic transmissions it is necessary to manually select a low gear. Manual transmission drivers will do this automatically. With 2WD vehicles there are additional considerations when using engine to brake in slick conditions:Regardless of front or rear drive, it is usually best to cease engine braking before entering a curve. The regular brake and especially ABS will distribute braking more equally and are less likely to cause understeer than FWD engine braking or oversteer compared to RWD engine braking.
because if you going down hill its faster because its a mountain
A crane can cross a road but, if it is going to travel along a road it will likely need a permit.
About 1.25 hrs
It takes a car 387 feet to come to complete stop when going 70mph.
It takes 233 Feet to stop.
If they were backing up, they would be going backwards... If they were braking, they wouldn't be going anywhere......
This is a difficult question to answer, since factors involving the condition of each vehicle, especially the brakes, road and weather conditions dictate how far the vehicle will travel before it comes to a rest.
In going away from the sun Mercury comes before Venus and Earth comes after.
it depends on the weight of the car and the condition of the road surface

It's going to be rated PG-13. However, it is possible if you are younger than 13 to see it if a parent or guardian comes with you.
A wider tire may decrease braking distance, but it depends on many factors.
