Answer:
230 mph
Step-by-step explanation:
Let speed of plane in still air be x. Therefore, when against the wind speed, the resultant speed is x-40 mph. Equally, when with the wind speed, the resultant speed is x+40 mph. The time is the same hence we can express these as ![\frac {475}{x-40}=\frac {675}{x+40}](https://tex.z-dn.net/?f=%5Cfrac%20%7B475%7D%7Bx-40%7D%3D%5Cfrac%20%7B675%7D%7Bx%2B40%7D)
By cross multiplication
675(x-40)=475(x+40)
675x-27000=475x+19000
200x=46000
X=46000/200=230 mph
