A Ray is composed of an origin and a direction. In addition, the direction is always normalized. So the best way is to use Ray.GetPoint() which will find a point a specified distance along the ray. This is equivalent to:

var v3Pos = ray.origin + ray.direction * distance;

If you have a figurative ray (i.e. an origin and a direction but not in a Ray class instance), you can use the above formula if you make sure the direction is normalized.
