Can average speed and average velocity be equal?
Also know, can average speed and average velocity be the same?
Speed is a scalar quantity while velocity is a vector quantity. Like this, if it is speed, you would just refer it to 2 m/s. So, average speed is the total distance taken over the total time taken (regardless of direction) while average velocity is the same whole thing, except it includes direction.
Beside above, what is the difference between velocity and average velocity? An average velocity really takes the distance covered in a given time and the average velocity will be the distance divided by time. A true velocity is an instantaneous quantity. The difference term is dX/dt where dt is an infintiesimaly small slice of time and dX is the change in in position during that time.
Furthermore, how do you find average speed and average velocity?
The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.
What is the formula for average speed?
Average Speed = (Total distance)/(Total Time) = (1800 + 1800)/(30 + 45) = 3600/75 = 48 km/hr. Hence the correct option here is C) 48 km/hr. So to find the average speed never use the formula of the averages but try to find the total distance covered and the total time taken.
