It is a beautiful weekend day, and you and four friends decide to spend it outdoors. Two of your friends just want to relax, while the other two want to get some exercise. You need some quiet time to study physics. To satisfy everyone, the group decides to spend the day on the river. Two peoplewill put a canoe in the river and just drift downstream with the 1.5 mile per hour current. The second pair will begin at the same time from 10 miles downstream. They will paddle upstream until the two canoes meet. Since you have been canoeing with these people before, you know that they will have an average velocity of 2.5 miles per hour relative to the shore when they go against the river current. When the two canoes meet, they will come to shore and you should be there to meet them with your van. You decide to go to that spot ahead of time so you can study while you wait for your friends. Where will you wait?
