Question

The distance a race car travels is given by the equation,
`d=v_(0) t+(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.
