How long did the train take to reach station B? ** Since the train takes 2 hours longer to go an equal distance as the car, to reach station B, the train took 4.5+2 = 6.5 hours.
How long did the car and the train take to reach station B? ** Together, the train and the car take a total of 6.5+4.5 = <<6.5+4.5=11>>11 hours to travel from station A to station B.
