Driving a vehicle with 20 inch rims.
Acceleration = delta velocity/delta time a = 70 m/s/35 seconds = 2 m/s2 ------------
You divide 400m by 20s to get: 400 m / 20 s = 20 m/s (which is a moderate speed for a vehicle)
The answer depends on the petrol consumption of the vehicle in miles/gallon km/metre etc.
Mils are a unit of measurement, comparable to degrees. On a compass 360 degrees is equivalent to 6400 mils. It is a measurement commonly used in the military because it can also be used to measure distance. At a distance of 1000 meters, 1 mil is equivalent to 1 meter.For example, if you know a vehicle is 4 meters wide and it is measured from a distance as being four mils wide you know it stands at a distance of 1000 meters.

In any driving location, it is generally agreed to be safe if you position yourself 3 seconds or more behind the vehicle in front of you.
3 seconds
What is following distance? Following distance is the space between your vehicle and the vehicle in front of you while driving. It's important for all drivers to maintain a safe following distance, so that they have time to safely stop in case the vehicle in front of them brakes abruptly.
At minimum 3 seconds. If the road conditions are adverse, it should be 5 seconds or more.

the distance/time in which you should be following at behind a vehicle
As a general rule, 3-5 seconds would be appropriate but it largely depends on the road conditions, your speed and the stopping capabilities of the vehicle that you are driving.The question to ask yourself is: If the vehicle in front come to a sudden halt, will I be able to stop without hitting them?If the answer is 'no' - you are not driving at a safe distance from the vehicle and you should back off.If the answer is 'yes' - you are leaving safe distance.
a driver behind your vehicle is trying to pass you
At least three seconds, more in adverse weather conditions.
False; you want to increase your distance from the vehicle you're behind.
