Best answer
Correct Answer - Option 1 : 1250/9

Given : 

Distance between Arunachal Pradesh and Gujarat = 2500 km 

Actual time taken by aeroplane to cover distance = 11 – 1 = 10 hours 

Formula Used: 

Distance = speed × time 

x km/hr = 5/18 × x m/s 

Calculation: 

Distance = speed × time

5000 = speed x 10 

Speed = 500 km/hr 

Speed of Aeroplane in m/s = (5/18) × 500 = 1250/9 m/s
