Tony is driving to visit a friend who moved to another state. For the first hour, he drives on the interstate at a constant rate of 60 mph. For the next two hours, he drives on a state highway at a constant rate of 45 mph. The last hour of the trip is on a hilly country road, which slows him down to a steady rate of 35 mph. What is the total distance that Tony will drive to reach his friend’s house?
