This will lie within the range specified at MotorWheel::getCirMM(); 
parameters 
unsigned int cirMM   
The value want to set 
 See:  MotorWheel::getCirMM() 
unsigned int getSpeedCMPM() const 
      Get the speed(centimeter per minute) 
This will lie within the range specified at GearedMotor::getGearedSpeedRPM().   
See:  GearedMotor::getGearedSpeedRPM() 
unsigned int setSpeedCMPM(unsigned int cm,bool dir) 
        Set the speed for motor 
This will lie within the range specified at GearedMotor::setGearedSpeedRPM(). 
Then you will see MotorWheel::getspeedCMPM()
