First you would need to figure out how many miles she can drive in 1 hour. By subtracting 200 from 350, you can see that in 3 hours, Sue drove 150 miles. If you take 150/3, you will find that she can drive 50 miles in 1 hour. By 5:00pm, Sue would have driven 400 miles.

Don't know about Utah. In Ky where I live the dealer must give the buyer a 30 day warranty of usability which is normally a 50/50 warranty, even if he bought the car as is. Contact the seller first and if not satisfied with his answer, contact your local county attorney for information on Utah law. Document everything in writing. Who you talked to, what was said, when, where, and the date and time.
