Using the given equation, replace s with 4 and solve for t:
t = 0.0119s^2 - 0.38s -0.0003
t = 0.0119(4)^2 - 0.38(4) - 0.0003
t = 0.0119(16) - 1.52 - 0.0003
t = 0.1904 - 1.52 - 0.0003
t = -1.3299
Rounded to the nearest hundredth t = -1.33
This means the runner would finish 1.33 seconds faster. ( Lower time)
