**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.
