Since the distance, d, traveled is the same for both trips,       d    =          (      480              mph            )              (      9              h            )        =    4320          miles      The time taken for the trip there, t, is the distance divided by the speed.      t    =                  4320                  miles                            432                  mph                      =    10          h
