Your answer is wrong or the question you're asking is wrong.
617.5 km/s was too low, and that's more than 300000 mph which you said was too high.
Which one is it, too high or too low? Or do you even know? Like I said you're either asking the wrong question or you yourself have the wrong answer.
Escaping from the gravitational pull of a spherical object such as a planet, moon or star is represented by V = Sqrt(2GM/R).
And we've used that to give you answers, but you say they're wrong and then go on to be ignorant of the FACT that you don't have your numbers straight.
FACT: You said 617.5 km/s was too low.
FACT: You said 300,000 mph was too high.
FACT: 617.5 km/s = 1 381 308.16 mph.
FACT: 1 381 308.16 mph > (is greater than) 300,000 mph.
So how can 617.5 km/s be too low when something less than it is too high?
Chelo your number sense is horrible, if you still don't understand the concept of one number being bigger than another then how can you even try to begin to understand the concept of escape velocities?
