Question 633370: 1.A plane travels from Orlando to Denver and back again. On the five-hour trip from Orlando to Denver, the plane has a tailwind of 40 miles per hour. On the return trip from Denver to Orlando, the plane faces a headwind of 40 miles per hour. This trip takes six hours. What is the speed of the airplane in still air?

You can put this solution on YOUR website! Let = the speed of the plane in still air = speed of plane from Orlando to Denver in mi/hr = speed of plane from Denver to Orlando in mi/hr
---------
1st trip:
2nd trip:
----------------
By substitution:
440 mi/hr is the speed of the plane in still air
check: mi
and mi/hr
OK
