The speed of wind and speed of plane in still air are 23 and 135
km/h respectively.
<u>Step-by-step explanation:</u>
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.

Answer:
WX = 31
Step-by-step explanation:
(65 + WX) = 2 (48)
(65 + WX) = 96
WX = 96 - 65
WX = 31
