While trying to make an important decision, your roommate paces back and forth along the hallway outside your door. Distracted by their pacing, you decide you might as well turn it into a physics problem! You define the doorway as your x = 0 reference point and measure your roommate's position using floor tiles as your unit of distance (defining motion to the right of the doorway as the "positive" direction). The stopwatch on your phone allows you to measure time in seconds. You notice that your roommate pauses to think at a position 2.5 tiles to the right of the doorway, when your stopwatch reads 5.7 seconds. They then wander back and forth for awhile, eventually pausing again at a position 17.0 tiles to the right of the doorway, when your stopwatch reads 53.8 seconds. What was your roommate's average velocity during this time interval? (Give your answer in tiles per second.)
