Wow PokeKing, you couldn't be more wrong. Infernape has a base speed stat of 108, whereas Blaziken only has a base speed stat of 80.
Now as for damage goes. Infernape attacks first. Add it's attack power with Earthquake's power and double it because it's super-effective. Then subtract it from Blaziken's poor defenese stat and HP. I'm going to add it up for you; keep in mind this isn't Infernape's or Blaziken's max attack and defense:
Attack Power + Move Power = Total Power
307 + 100 = 407
Total Power x Super-effective Hit = New Total Power
407 x 2 = 814
New Total Power - Defense Power = Damage Dealt
814 - 239 = 575
HP - Damage Dealt = Nothing Left
364 - 575 = 0
There it is. As long as no items are attached that enhance power, speed, evasiveness, or durability, Infernape wins with a OHKO.
