1. The problem statement, all variables and given/known data At maximum speed, an airplane travels 2400 miles against the wind in 6hrs. Flying with the wind, the plane can travel the same distance in 5hrs. Let x be the maximum speed of the plane and y be the speed of the wind. What is the speed of the plane with no wind. 2. Relevant equations well first of all, I need to come up with an equation of inequality or linear for this problem. 3. The attempt at a solution x= max speed y=speed of the plane known:2400m/6hrs against wind 2400m/5hrs with wind can someone give a hint of an equation to approach this problem?
