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.
