It will take 6.25 seconds for the dino to reach 25 m/s and the human would have traveled 37.5 meters and the dino would have traveled 78.115 meters.
6x + 40 = 2(x^2)
X^2 - 3x - 20
6.217 s
6 s using sig figs.
Assuming the human attempts to maximize his time to stay alive.
That assumes that the human will attempt to run rather than fight back and that the human dies on the spot where the velociraptor catches him/her. I mean it is possible that the raptor might miss while making an jump on the human and even after being hit the human might crawl for a few more meters.
Personally I would try to fight. Unless the scenery has some obstacles or some building where I could barricade myself I would probably get caught sooner or later. Instead by fighting back immediately I will face the velociraptor head on and I haven't exhausted myself by running.
Also the question was HOW FAR WILL YOU GET BEFORE THE RAPTOR CATHES YOU not HOW MUCH TIME DO YOU HAVE LEFT.
