An athlete completes a 100-meter race in 20 seconds. At the start of the race (\(t=0\) s), his distance from the starting line was 0 m. At the finish line (\(t=20\) s), his distance was 100 m.
Calculate his average speed (the rate of change of distance with respect to time) over the course of the race.
Average speed \(=\)
