The vehicles will have 10 hours to complete the course, but they only win the million if they do it in under 6. At least that's my understanding from the website.
Keep in mind that the vehicle has to complete the course in under 6 hours to win the prize money. The scale of the robot you seem to be proposing is inadequate to the speeds that the vehicle would have to maintain. 250 mi/6 hr = about 41 miles an hour avg. speed.
