Suppose a plane flying west a distance of 600 miles take 6 hours .The return trip take 5 hour . Find the airspeed of the plane and the effect wind resistance has on the plane?

Answer 1

The upwind speed is 100 mi/hr, and the downwind speed is 120 mi/hr. So, if the plane's speed is p and the wind speed is w (clearly, from the west),

p+w = 120
p-w = 100
