Suppose Driver A and Driver B's trips involve same number of miles and deliveries. The only difference is: Driver A's trip includes driving on a congested highway during the rush hour, and Driver B's trip does not. If the regression model in the video predicts that Driver A's expected trip time is 9.5 hours, then what is the expected trip time of Driver B? State answer in hours rounded to 1 decimal digit (e.g., 5.6)
