It is called a definition.
The definition of speed is the size/magnitude/measure of an object's velocity. Average speed = distance divided by time
The average rate of movement, for example the number of feet traveled in a certain number of seconds, or the number of miles traveled in a certain length of time.
Average speed is an average value of speed over a given time. If your speed is constant (not changing), then your average speed will equal your speed at any given moment in time.
Distance divided by time has the dimensions of speed (magnitude of velocity). The (distance an object travels) divided by (the time it takes to travel that distance) is a definition for the object's average speed.
It is called a definition.
The average speed of an object in an interval of time is the distance traveled by the object divided by the duration of the interval.
distance taken divided by the total time
The definition of speed is the size/magnitude/measure of an object's velocity. Average speed = distance divided by time
The average speed of particles in a substance is determined by the temperature of the substance. At higher temperatures, particles move faster, while at lower temperatures, particles move slower. This average speed is related to the kinetic energy of the particles.
average velocity
Average speed is defined as the total distance traveled divided by the total time taken to travel that distance. It gives a measure of how fast an object is moving on average over a certain period of time.
The average rate of movement, for example the number of feet traveled in a certain number of seconds, or the number of miles traveled in a certain length of time.
You are supposed to use the definition of "average speed", and simply divide distance by time. The answer will be in meters/second. If you want to convert that to kilometers/hour, multiply the result by 3.6.
The speed of something in a given direction.
Average speed is an average value of speed over a given time. If your speed is constant (not changing), then your average speed will equal your speed at any given moment in time.
Any speed is distance covered/time to cover the distance .Whenever you calculate a speed using this definition, the answer you getis the average speed during the time it took to cover the distance.The same units are used to describe any speed, whether it's average orinstantaneous speed.(any unit of length)/(any unit of time) is a perfectly good unit of speed.
