In some cases, they are too busy, unwilling, or just don't like completing surveys. Indeed, Nonresponse bias usually occurs when the ones who responded are different in many ways from nonrespondents.

<h3>What is the overall
stopping distance at 20 miles per hour?</h3>
In the 45 feet between perception and reaction, an automobile will move at 20 mph (30 feet per second x 1.5 seconds). After applying the brakes, the vehicle travels 64 feet in total, or around 19 feet, before coming to a stop.
When moving at less than 40 mph, you must maintain a minimum of one second of separation for every 10 feet your vehicle is long, according to the rule of seconds. If your speed is greater than 40 mph, add a second.
Thus, option D is correct.
