"For me it is easy to run fast."
Translation:Pentru mine este ușor să fug repede.
I thought repede and rapid were interchangeable, but my answer with rapid was not accepted.
"rapid" is an adjective. You can be "rapid", but you can't run "rapid".
Thanks. I thought I saw "rapid" used as an adverb in another exercise, but I may have been mistaken. :)
