An airplane flying with the wind takes 5 hours to travel a distance of 1500 miles.

The return trip takes 6 hours flying against the wind.

What is the speed of the airplane in still air and how fast is the wind blowing?

Respuesta :

Answer:

Step-by-step explanation:

1500 = (a + w)5

1500 = (a - w)6

(a + w)5 = (a - w)6

5a + 5w = 6a - 6w

         11w = a

1500 = (11w + w)5

 300 = 12w

     w = 25 mph

a = 11(25) = 275 mph
