The speed of the plane in still air is how many mph?
The speed of the wind is how many mph?
I have major problems with word problems can I get some help with this one? Thanks Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! If a plane can travel 490 mph with wind and 430 mph against the wind,
find the speed of the plane without a wind and the speed of the wind.
:
Let s = speed of plane in still air
Let w = speed of the wind
:
Two simple equations
s + w = 490
s - w = 430
--------------adding eliminates w, find s
2s = 920
s =
s = 460 mph in still air
:
I'll let you find the speed of the wind
