Question 28980: hey this problem made my brain literally bust please help I need a quick response
It takes a plane 30 minutes longer to fly from Boston to Los Angeles at 525 mph then it does to return at 600mph. How far are the cities? How long does it take to go? Return?

LA to Boston Data:
rate=600mph; Let time=x hrs
Then
Boston to LA Data:
rate =525mph; time= x+1/2
EQuATION:
distance = distance
and distance =(rate)(time)
600x=525(x+1/2)
600x=525x+525/2
75x=525/2
x=7/2 hrs
Distance = 600(7/2)-2100 miles
