An airplane flew 4 hours with a 25 mph tail wind. the return trip against the same wind took 5 hours. find the speed of the airplane in still air. this similar to the current problem as you have to consider the 25 mph tailwind and headwind. plane on outbound trip of 4 hours with 25 mph tailwind and return trip of 5 hours with 25 mph headwind let r = the rate or speed of the airplane in still air. let d = the distance
a. write a system of equations for the airplane. one equation will be for the outbound trip with tailwind of 25 mph. the second equation will be for the return trip with headwind of 25 mph.
b. solve the system of equations for the speed of the airplane in still air.
