Laura's piano teacher estimated that her monthly piano practice should take her 4 3/4 hours per week. Laura said that last week she practiced for 192 minutes, which she says is more than 4 3/4 hours. How much more or less did Laura practice piano than what her teacher estimated? (60 minutes = 1 hour)
