<PRE><B>Question 134562</B>
It takes a plane 40min to fly from Boston to Los Angeles at 525mi/h than it does to return at 600mi/h. How far apart are the cities?
My Chart
r * t =d
trip 525 * (t+(2/3)) = 525t + 525(2/3)
return 600 * t = 600t
t=time in hours
600t=525(t+(2/3))
600t=525t + 525*(2/3)
-525t -525t
75t=525(2/3)
divide by 75 to get and t= 4 2/3 = 14/3
------------------------
distance from Boston to LA = (14/3)*600 = 14*200 = 2800 miles
=====================
