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.

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.

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.

A cruise ship travels 1900 miles per trip. There are a total of 4 stops the ship makes, and the distance to the first stop is 460 miles. If the variable d stands for the distance left to travel after the first stop, which of the following choices is the most reasonable value for d?1,500 miles
