A bicyclist, starting from rest, speeds up for $$5.0\text{ s}$$. The magnitude of her acceleration during this time interval is $$a_1$$. She then stops pedaling and immediately begins coasting to a stop with an acceleration magnitude of $$a_2$$. If the bicyclist travels a total distance of $$45\text{ m}$$ and for a total time $$\Delta t = 15.0\text{ s,}$$ what was the maximum speed reached by the bicyclist?
