If the average speed and the time of travel are known, the distance travelled can be calculated by rearranging the definition to. Using this equation for an average speed of 80 kilometres per hour on a 4-hour trip, the distance covered is found to be 320 kilometres.ifferent from instantaneous speed, average speed is defined as the total distance covered over the time interval. For example, if a distance of 80 kilometres is driven in 1 hour, the average speed is 80 kilometres per hour.
