3.
At some stops, a certain bus picks up 5 people. At other stops, it picks up 2, and at the same time, it lets go of 5. There are no other stops but these. It starts its run empty and picks up five people. At the end, it has 11 people aboard. If the number of stops is greater than 17, what is the least number of stops the bus makes?
