Suppose the equation for the velocity of a sports car is given by:
V(x)=100(1-0.9^x) where V(x) is in feet per second and x measures the seconds since acceleration began, 0 < x < 60. How far will the car travel in the first 30 seconds?

Since the area for 0 < x < 30 is an irregular shape, we can't use one of our known area formulas. We will estimate the are by making rectangles.
