my teacher left my whole class completely lost this morning. He assigned practice problems, but I don't even know where to start. I would learn from the book. but the only book for this class is a workbook. Please help! It says:

The average car today weighs 3510 pounds, and when accelerating from rest, covers 0.250 mile in 15.0 seconds. Determine the cars average velocity, final velocity, and average acceleration for the trip.
