"At what speed does he run?"

Translation:À quelle vitesse court-il ?

January 14, 2018



À quelle rapidité court-il? Why this sentence wasn't correct.


And "la vitesse" is a unit of measure, which "la rapidité" is not.


A difference in nuance, I suspect. Rapidité tends to be used in a figurative sense meaning "quickness", speediness", "promptness", "briskness", "swiftness" etc of service or response to a letter or request.

On the other hand vitesse is used more in relation to actual speed, velocity and physical movement.


What kind of question is this? Yeah right, I always carry a radar to mesure the speed of random people...
