A runner is warming up for her event on a circular track with a diameter of 102 m. She starts by walking 1/5 of the way around the track in 177 s, then sprinting the next 3/5 of the way around the track in 127 s, before walking the final 1/5 of the track back to where she started in 178 s. What is the magnitude of the runner's average linear velocity from start to finish of her warm-up lap
