Question 1040149: if an airplane has a tail wind, the wind increases the speed of the plane by that amount. Similarly, a headwind decreases the speed of a plane by that amount. Suppose a plane which can fly at 250 mph in no wind flies 350 miles in head wind and 390 in a tail wind. What is the speed of the wind

Answer by josgarithmetic(39620) (Show Source): You can put this solution on YOUR website!
w, wind speed
r, airplane speed without wind
r=250

WHAT amounts of time for those 350 miles and 390 miles?
t time for the tail wind travel
x time for the headwind travel

------Not much more can be done. Three unknown variables but only two equations.

Hey,

your condition is wrong.
There is a mistake in your condition. (May be, more than one mistake!)
Read it and find a mistake.
