Mark Lane approves study abroad documents for the University of Utah. Students must wait in line with their forms outside Mark's office. One student at a time is allowed in his office and Mark takes precisely 25 minutes to evaluate each students set of documents. On average 2.2 students per hour go to his office and they spend on average 160 minutes trying to get their forms approved (time waiting in queue plus time in Marks office having him evaluate their documents).

What is the average time (Tq) at Mark's office in minutes?
