Answer:

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 = [tex]\frac{Distance}{Time}[/tex]

So,  S 1 =  [tex]\frac{D 1}{T 1}[/tex]

Or,   S 1 =  [tex]\frac{3060}{3}[/tex] = 1020 kmph

Similarly

Speed of plane with the wind    = [tex]\frac{Distance}{Time}[/tex]

Or,    S 2 =  [tex]\frac{D 2}{T 2}[/tex]

Or,     S 2 =  [tex]\frac{7560}{6}[/tex] = 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
