Correct option is
D
720 kmph
Distance = (240 × 5) = 1200 km.
Speed = Distance/Time
Speed = 1200/(5/3) km/hr. [We can write 1
3
2
hours as 5/3 hours]
∴ Required speed = (1200×
5
3
) km/hr=720 km/hr.

Answer:
Step-by-step explanation:
Let the speed of aeroplane be x
Distance = V x T
3540x4= 14160
Let the speed of train be y
Distance= V x T
240 x 3= 720
Therefore, the ratio of the speed of the train to the speed of aeroplane = 14160/ 720
= 177 : 9
