An aircraft flew 6 hours with the wind. the return trip took 7 hours against the wind. if the speed of the plane in still air is 504 miles per hour more than the speed of the wind, find the wind speed and the speed of the plane in still air.

Sorry I tries to work it out but could not get it

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
