For several weeks, MMDA has been recording the speed of freeway traffic in EDSA. The data suggest that between 1:00 pm and 6:00 pm on a normal weekday the speed of traffic is approximately given by the function below. S(t) = t³ - 10.5t² + 30t + 20 miles per hour, where t is the number of hours past noon. a. At what time between 1:00 pm and 6:00 pm is the traffic moving the fastest? b. At what time between 1:00 pm and 6:00 pm is the traffic moving the slowest?
