Question below as it was too long plz help?

A hare and turtle compete in a race over a course 3.20 km long. The turtle crawls straight and steadily at its maximum speed of 0.550 m/s toward the finish line. The hare runs at its max speed of 12 m/s toward the goal for .800 km and then stops to tease the turtle. How close to the goal can the hare let the turtle approach before resuming the race to which the turtle wins in a photo finish?
