A regularity rally, also called time-speed-distance or TSD rally, is a type of motorsport rally with the object of driving each segment of a course in a specified time at a specified average speed. The rally is usually conducted on public roads, but sometimes includes off-road and track sections.
Two kinds of drive cycle can be made. One is DISTANCE DEPENDENT (SPEED versus DISTANCE versus ALTITUDE) and the other one is TIME DEPENDENT (SPEED VS TIME VS GEAR SHIFT). The DISTANCE DEPENDENT is the actual replica of the test road whereas TIME DEPENDENT is the compressed version of the actual time taken to conduct the test on road.
The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; [2] the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is the magnitude of velocity (a vector), which indicates additionally the direction of ...
The maximum speed is 56.7 mph (91.2 km/h) and the average speed is 19.6 mph (31.5 km/h). The cycle has two phases: a "cold start" phase of 505 seconds over a projected distance of 3.59 mi at 25.6 mph average speed, and a "transient phase" of 864 seconds, for a total duration of 1369 seconds.
In terms of judging a person's speed, the best method of timing is through lasers which start and stop the times when passed through. A laser start (from a stationary position) is more accurate for measuring pure speed as it does not register a runner's reaction time, however, this method of timing a 40-yard dash can affect the accuracy by as much as 0.5 seconds with the manual stopwatch method.
Free response tests are a relatively effective test of higher-level reasoning, as the format requires test-takers to provide more of their reasoning in the answer than multiple choice questions. [4] Students, however, report higher levels of anxiety when taking essay questions as compared to short-response or multiple choice exams.
WORCESTER, Mass. – Local police in this central Massachusetts city used excessive force and engaged in “outrageous” sexual contact with women during undercover operations, a two-year civil ...
The three second rule is a time for the defensive driver to judge the minimum safe trailing distance to help avoid collisions under ideal driving conditions. The red car's driver picks a tree to judge a two-second safety buffer. The two-second rule is a rule of thumb by which a driver may maintain a safe trailing distance at any speed.
