The finishing time for a runner completing the 200 m dash is affected the tail wind speed, s. The change, t, in a runners performance is modeled by the function below:
t=0.0119s^2-0.308s-0.0003
Predic the changein a runners finishing time with a wind speed of 4 meters/second NOTE: a negative answer means the runner finishes with a lower time
