Question 904734: can u help me with this word problem? it involves the formula D=rt+rt
It takes a plane 40 minutes longer to fly from Boston to LA at 525mph than it does to return at 600mph. How far apart are the cities? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! 525*(x+2/3)=600x
525x+2/3*525 )=600x
2/3*7=x
14/3 hr=x la to boston
boston to la 14/3+2/3=16/3 hr
600*14/3=200*14=2800 miles
