To find the average rate (speed) of a car traveling on a highway, the distance traveler is divided by the time: R=D/T. If the distance is D=36/x^2-36 miles and the time is T=6x^2+6x/x^2+7x+6 hours, find a simplified expression for the average rate of the car.
a) 1/x
b) 6/x-6
c) 6/x^2-6x
d) 1/x^2-6x
