I am having trouble with this one. I am more interested in the steps than the answer.

A trip from Here to There is 2108 miles. If one car drove 6mph faster than a truck and got There 3 hours before the truck, find the speeds of the car and truck.

I think the car's speed is (truck's speed) + 6, its time is (Truck's time) - 3, and its distance is 2108, but I am unable to get an answer. I have manipulated the d=rt formula but to no avail. Any help would be appreciated.
