Great question !
The rate at which an object covers distance, without worrying 
about the direction it's moving, is the object's SPEED .
When the direction is also given, then you have the object's VELOCITY.
This question is important.  It gives us a chance to point out that 
"velocity" is not just a fancy word for speed that you use when you 
want to sound smart.  There's actually an important difference between 
'speed' and 'velocity'.
