The distance a race car travels is given by the equation, d=v_{0} t+\frac{1}{2} at^{2}, where v_{0} is the initial speed of the race car, a is the acceleration and t is the time traveled. Near the beginning of a race, the driver accelerates for 9 seconds at a rate of 4m/s^{2}. The driver's initial speed was 75 m/s. Find the driver's average speed during the acceleration.
