Whilst i agree with fdmaxey's reasoning for using the same verb with a single sentence there is actually a difference between the two words although not really used here. "To hurry" is do do something quickly - you are still doing it with the same level of competence just quicker. "To rush" suggests that you are doing it too quickly and probably not as well - you might be cutting corners, so to speak. Although I agree this isn't the intention in this sentence it is useful to remember the distinction in the future.
