Problema Solution
An airplane took 3 hours to fly 600 miles against a headwind. The return trip with the wind took 2 hours. Find the speed of the plane in still air and the speed of the wind.
Answer provided by our tutors
x=plane
y=wind
x-y=600/3=200
x+y=600/2=300km
so so speed of plane =250
nd wind speed=50
