Plotting start-up

The fastest speed shown on the graph is the initial slope at zero on the time axis, 

This would be the result if the runner could start the race at his maximum speed, or another way of combining these two numbers is to say that if the runner had started a distance = Vmax..To (i.e. about 25 m) before the line, then he would have been up to maximum speed by the starting line (neglecting the very small amoimt of fatigue during that time).
