<PRE><B>Question 1029290</B>
 one plane travels 80 mph faster than another. While one travels 1750 miles, the other travels 950 miles. find the speed of each plane. 
--------------------
faster plane DATA:
rate = x + 80 mph ; distance = 1750 ; time = 1750/(x+80) hrs.
-----------
slower plane DATA:
rate = x mph ; distance = 950 ; time = 850/x hrs
------
Equation::
time = time
1750/(x+80) = 850/x
-----------------------
1750x = 850x + 80*850
--------------------------
900x = 80*850
------
x = 75.56 mph
x+80 = 155.56 mph
---------------
