You can put this solution on YOUR website! Judy can bike at 12 mph when there is no wind. Against the wind Judy bikes 8 mph in the same time it takes to bike 14 miles in the wind. Determine the speed
------------------
This is not a reasonable question for several reasons.
Drag due to wind is not a linear function, it's cubic.
There is no reason to assume Judy doesn't use more power against the wind than with it, or vice versa.
Bicycles travel on the ground, not in the air. This could apply to an airplane, but not a bicycle.
