    Answer: (2) 40 km/h
    Explanation:-
    The speed of the bus = 60 km/h
    Time taken by bus to covered the journey = 6 h
    The distance covered by bus = 60 x 6
    = 360 km
    Now, The speed of the bus to cover the same distance in 9 h = 360/9
    = 40 km/h
    hence, the answer is (2) 40 km/h.
