Flying to Kimpala with a tail wind a plane averaged 158km/hr. On the return trip the plane only average 112km/hr. While flying back into the same wind find the speed of the wind and the speed of the plane still in air?

The speed of wind and speed of plane in still air  are  23  and  135 km/h respectively.

Step-by-step explanation:

Let the speed of wind and speed of plane in still air  are  w  and  p km/h respectively.  

The effective speed on onward journey was  

 ................(1)

The effective speed on return journey was  

..............(2)

Adding equation (1) and equation (2) we get,  

⇒

⇒

⇒

Putting value of in we get:

⇒

⇒

⇒

Therefore ,The speed of wind and speed of plane in still air  are  23  and  135 km/h respectively.
