2. s <= getS()
3. s = 0 if t = 0
4. s = getS() if t = getT()

Specified by:

calcS in interface SpeedAgainstTime

Returns:

s

calcT

public double calcT(double s)

Description copied from interface: SpeedAgainstTime

Returns the time taken to travel distance s. The returned value, t, satisfies the following conditions:

1. t >= 0
2. t <= getT()
3. t = 0 if s = 0
4. t = getT() if s = getS()

Specified by:

calcT in interface SpeedAgainstTime

Returns:

t
