    Answer:

    the total trajectory length is 349.39 km

    Explanation:

    for the first trajectory

    Time taken in first trajectory = First trajectory length /velocity  = 180 km/95 km/h = 1.894 hours

    therefore since the total time is 4.5 hours

    Time taken in second trajectory =  Second trajectory length /velocity  

    4.5 hours- 1.894 hours = Second trajectory length / 65 km/h

    Second trajectory length = 169.39 km

    therefore the total trajectory length is 180 km + 169.39 km = 349.39 km
