Moving an object a specific distance

Ok so what I’d like to do is basically just create an object that is able to wander around on its own. Maybe I am going about this the wrong way, but so far here’s what I have. I want the object to randomly pick a degree in which it will rotate, and then randomly assign a distance for the object to travel. I was thinking i could tell the object to rotate, and them move it forward in the direction it turned to.

 var speed = 5.0;
 var distance : int;
 var direction : float;
 
 function Generate(){
     distance = Random.Range(1,5);
     direction = Random.Range(1,360);
     SpawnMove();
 }
 
 function Start(){
     InvokeRepeating("Generate",0,5);
 }
 
 function SpawnMove(){
     transform.Rotate(0, direction, 0);
 }
