    Answer: (4) 720 kmph
    Explanation:-
    The speed of an aeroplane  = 240 km/hr
    Time taken by aeroplane = 5 hr

    Total distance covered by an aeroplane = 240 x 5
    = 1200 km

    If it covered the same distance covered in 5/3 hr.
    Then, the speed of an aeroplane = 1200 x 3/5
    = 240 x 3
    = 720 kmph
    Hence, the answer is (4) 720 kmph.
