With scenario at standard running speed ('50' or middle of slide bar), something like the following should work: 
private int qTimer, qValue;

public void act()
{
    if (qTimer == 0)
    {
        qValue = Greenfoot.getRandomNumber(10);
        qTimer = 180;
    }
    else qTimer--;
}

For you, right now, not really much. However, a private field is only accessible within the class it is declared in (or, rather, by the object the field belongs to). If not private, other classes, or objects, in your project would be able to access and change the value of the fields. Since the fields are only pertinent to the object they were created for, making them private only makes sense.

Show codes. Also, it would never increase, anyway. It would be set (from zero) to 180 and decrease from there.
