A doctor can type 30 words per minute as a patient is describing his symptoms. Transcription software an type 150 words per minute. If the patient talks for 2 minutes, what is the difference in the number of words the doctor can type compared to the transcription software?
The doctor can type 30 words per minute * 2 minutes = <<30*2=60>>60 words.
The transcription software can type 150 words per minute * 2 minutes = <<150*2=300>>300 words.
The difference between the number of words the doctor can type versus the transcription software is 300 words - 60 words = <<300-60=240>>240 words. Answer: \boxed{240}.
