Velocity is a vector quantity and average velocity can be defined as the displacement divided by the time. Set up the formula for average speed given two speeds used for the same amount of time. Average Speed Total distanceTotal Time 1800 180030 45 360075 48 kmhr.
The formula is s a b 2 displaystyle sfrac ab2 where s displaystyle s equals the average speed a displaystyle a equals the speed for the first half of the time and b displaystyle b equals the speed for the second half of the time.
Vector it has magnitude direction SI unit for Average Velocity. The average velocity of a body in a certain time interval is given as the displacement of the body in that time interval divided by time. Speed being a scalar quantity is the rate at which an object covers distance. There are 1000 meters in 1 kilometer and so 1 kilometer is.
