Question 795257: An airplane makes a trip in 4.3 hours flying with a headwind. The plane makes the trip back in 3.9 hours with a tailwind. If the windspeed is 10 miles per hour find the speed of the airplane. Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Airplane speed = x
Airplane flying with headwind = x - 10
Airplane flying with tailwind = x + 10
4.3 * (x - 10) = 3.9 * (x + 10)
4.3x - 43 = 3.9x + 39
Collect like terms:
4.3x - 3.9x = 39 + 43
0.4x = 82
x = 205 mph
This is the airplane's speed.
Hope this helps.
