Average speed is calculated by dividing the total distance that something has traveled by the total amount of time it took it to travel that distance.
Average Speed is important to understand the rate at which a journey takes place. Throughout a journey, the speed may vary from time to time. In that case, finding the average speed becomes important to have an estimate of the rate at which the journey is completed.
To get average speed, s , divide total distance by elapsed time: Dt. To get elapsed time, t , divide total distance by speed: Ds. To get distance, D , multiply speed times the amount of time: s × t
