A trucking company considered a multiple regression model for relating the dependent variable total daily travel time for one of its drivers (hours) to the predictors distance traveled (miles) and the number of deliveries of made. After taking a random sample, a multiple regression was performed and the output is given below. What is the multiple regression equation?
