Two cars leave an intersection at the same time. One drives east while the other travels south at 15 miles per hour faster than the other. After 3 hours, the cars are 225 miles apart. How fast is the southbound car driving?

I have an economical car, but it really is not when you driving really fast. They say its not the car, but how you drive your car. I would suppose a Prius would not be efficient if you are driving 80 miles per hour with such a small engine compare to a BMW M3.
