A train leaves Colorado Springs at 9:00 am bound for Boulder Colorado, 100 miles away. It travels at 50 mph and has to pick up passengers every 25 miles. Each stop takes 10 minutes, and after each stop, the increased passenger weight causes the train's speed to decrease by 10 percent. When does the train arrive in Boulder?

i'm having a little trouble with this word problem. Are there really only 3 stops to pick up people?
