Rapidement vs vite

Question

So, rapidement and vite are synonymous; however when I typed in vite for Henri runs quickly, it was marked as incorrect.  Because they are synonymous, I feel that «vite» should be included as a correct response as well as rapidement.

Bonjour Nicholas,
I would tend to agree with your reply; however, in my French thesauraus rapidement and vite are listed as synonymous.

Nicholas DEVINE · Answer

Not synonymous, rapidement is used with speed and probably better thought of as fast rather than quick.

Eleanor Walker-Jung · Answer

If Henri runs quickly, vite should be vitement, I think, but the dictionary doesn't agree. Rapidement, vite as you believe or vitesse are possible.
