Question

Who would win a race between a fly and the world's fastest man?

Answer 1

that would not be a contest,even if you could get the fly to fly in a straight line.

A fly does not fly nearly as fast as a good sprinter, and they can not fly at top speed for at least 100 meters which is the shortest outdoor distance.

A human would win this race.  

Answer 2

human. usain bolt would not lose to a fly . usain bolt on one leg wouldnt lose to a fly but to answer your question the human would.
