You can put this solution on YOUR website! An airplane flew for 6 hrs. with a tail wind of 60km/hr. The return flight against the same wind took 8 hours. Find the speed of the airplane in the still air.
Let x = speed (km/hr) of plane in still air
then applying the distance formula:
6(x+60) = 8(x-60)
6x+360 = 8x-480
360 = 2x-480
840 = 2x
420 km/hr = x
