An airplane flew for 6 hours with a 22km/hour tailwind. The return flight against the same wind takes 8 hours. Find the speed of the plane with no wind and windspeed.
speed of plane with no wind --- x km/h
speed of wind ----- 22 km/h
distance of first trip = 6(x+22)
distance of return trip = 8(x-22)
but aren't the distances the same ?
take it from here.
