Mathmatic genies click here --> a Puzzle needs to be solved!

[LP]

So guys...

I'm in a bit of trouble here... I really need someone to give me a mathmatic formular for the following problem (If possible with the possible lack of information):

I've got to animate a dragon so it walks across a 740x486 screen... Cool...

It has to be done in 200 frames... Cool...

The dragon comes from non-visibility -> then goes across screen -> then disapeares into non-visability again... Cool...

The dragon is just as long as the screen (486pix)... Cool...

I've decided that one step should take approx. 20 frames... Cool...

I need to know how many steps the dragon has to take to do a full screen pass in 200 frames...

-Or even better!: A formular were I get X as the number of frames to use for one "step-routine" (From A to B were I can circle the whole anim so it looks like the dragon walks... A-B-A-B-A-B etc.)

-I don't know if this is complete bull to you but at least I tried explaining it...

-Thanks!

@seer

Sorry yeah I mistyped it there I ment 720!
-And trust me I've watched more that one movie to get that thing moving (Sounded quite porno) :-)

@Wain
You have understood me!
-Thank you!

@Hardboy
Where from in København? +Thanks

I know it's a bit of a clumsy explain but the answers you've come up with is great and will work for me (I'm bad with setting up my own formulars as you might see!?)

Thanks a bundle dudes!

@Doobrey

Sorry I think it's my bad explaining again...
My overall idea was to get pixel lengths/frames not actual steps...

:-(

I think Wain is right because first we have the whole length of the dragon outside the screen to the left, then the walk across and finally the length of the dragon outside on the right side...
so it's actually 3*DragonWidth as far as I have understanded...
