60 MPH = 88 fps. (fps=1.467 * MPH). If the vehicle deceleration rate is 20 fpsps, then stopping time = 88/20 = 4.4 seconds. Since there is a 1 second delay (driver reaction time) in hitting your brakes (both recognition and reaction time is often 2 seconds), the total time to stop is 5.4 seconds to 6.4 seconds.
Depends what car it is.
45 feet
It depends on the road conditions, as well the state of your brakes.
If the man runs for one hour at a speed of 8 miles per hour, he will cover a distance of 8 miles. Since he runs for a full hour without stopping, the entire distance is achieved at that constant speed. Therefore, the total distance covered in that hour is simply the product of speed and time, which is 8 miles.
The stopping distance at 30 miles per hour typically ranges from 75 to 100 feet, depending on factors such as road conditions, vehicle type, and driver reaction time. This distance includes both the perception and reaction time (approximately 44 feet) and the braking distance (around 30 to 56 feet). It's important to account for these variables to ensure safe stopping distances in different scenarios.

Stopping a vehicle with good brakes from 20 miles per hour under good conditions typically requires a distance of about 20 to 30 feet. This distance can vary based on factors such as the type of brakes, tire condition, and road surface. Generally, the stopping distance includes the reaction time of the driver and the braking distance itself.
5o miles per hour is 73.3 feet per second. The average stopping distance for the breaks at that speed is 128 feet. Now add to that the average reaction time for a driver at that speed which is 3/4 second so we add 55 feet gives us a total of 183 feet.
3 x 45 = 135 miles total distance. You are averaging 45 miles per hour over the 3 hour period.

Three hours at 62 mph is a distance of 186 miles.
