1. Hendrix and Tacey were to compete in a race over a course 2km long. Tacey crawls straight and steadily at its maximum speed of 0.4m/s toward the finish line. Hendrix runs at its maximum speed of 10m/s towards the goal for 1.7km and then stops to tease Tacey. How close to the goal can Hendrix let Tacey approach before resuming the race, which Tacey wins in a photo finish? Assume that when moving, both contestants move steadily at their respective maximum speeds.
