Question 308388: I have difficulty setting up word problems- not sure what I should be asking myself. Problem: A plane travels 460 mph with the wind, 400mph against the wind. Find speed in still air. Thanks. Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! Let the plane speed be P, the speed in still air.
Let the wind speed be W.
Travels with the wind, the plane's true speed is,
Travels against the wind, the plane's true speed is,
Since rate*time=distance.
Usually you either know T1 and T2 and solve for D or some other combination of variables.
