    Answer:1) the total distance is the sum of the two distances

    60 km +  45 km = 105 km

    2) The displacement is the net movement, or the difference between the initial position and the final position

    Call x the initial position, then the final position is x + [60km – 45km]

    And the displacement is x + (60km – 45km) – x =60km -45 km = 15 km
