As pieCRUST and ewok stated, a five minute experience feels like a twenty five minute experience, which still feels like a five minute experience, but with twenty five minutes of experience in it. Therefore, each of the five seemingly five minute spans, which are in fact each just a minute long, contains about five minutes of experience. So in twenty five five-minute minutes, you get about one hundred and twenty five minutes of experience, which is six hundred and twenty five minutes, or nearly ten and a half hours!
