Flying against the wind, an airplane travels 3060 kilometers in 3 hours. flying with the wind, the same plane travels 7560 kilometers in 6 hours. what is the rate of the plane in still air and what is the rate of the wind ?

The speed of plane against wind S 1 = 1020 kmph     And

The speed of plane with wind S 2      = 1260 kmph

Step-by-step explanation:

Given as :

The distance of airplane against the wind = D 1 = 3060 km

The time taken in against the wind             = T 1 = 3 hours

The distance of airplane with the wind       = D 2 = 7560 km

The time taken in with the wind                   = T 2 = 6 hours

Now, Speed of plane against the wind =

So,  S 1 =  

Or,   S 1 =   = 1020 kmph

Similarly

Speed of plane with the wind    =

Or,    S 2 =  

Or,     S 2 =   = 1260 kmph

Hence The speed of plane against wind S 1 = 1020 kmph     And

            The speed of plane with wind S 2      = 1260 kmph   Answer
