How do you find the total distance for a trip that involves turn-arounds?
You decide to get some extra exercise by biking to school in the morning, and your school happens to be 4 miles from your house. So you get up in the morning and bike toward school, but you overshoot it, and you end up 20 miles away from your home. Then you quickly turn around and you come back to school all in time for your first class. What is the total distance of your path from your home to the school?
