Question 932111: it takes an airplane 1 hr 30 min to fly 600 km against the wind. The return trip with the wind takes only 1 hr. Find the total flying time for the round trip if there was no wind? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! r + w = 600kph r - w = 400kph
2r = 1000kpr
r = 500kph, the speed of the plane
....
w/o wind
t = 600k/500kph = 1.2 hr
