If a train can travel 480 miles per hour with the wind at 420 miles per hour against the wind, find the speed of the plane without wind and the speed of the wind.
-------------
The plane's airspeed is the average = (480 + 420)/2
= 450 mi/hr
-----------
The windspeed is the difference = 480 - 450
= 30 mi/hr
---------------------
A train would not be significantly affected by the wind.
