What was the mph for the fastest man?

The fastest man is Usain Bolt who holds the world record in the 100 meter dash at 9.69 seconds. That would work out to about 23 MPH.

1616 meters in a mile

1616/100=16.16

16.16 x 9.69 = 156.59 seconds in a mile

156.59/60= 2.6 minutes

60 minutes/2.6 minutes = 23 MPH

Actually Usain Bolt has not beaten Tyson gay in a race since the 2008 Olympics and that was because of an injured hamstring that Gay received qualifying for the Olympics....Meaning Tyson Gay is the worlds fastest man
