one plane travels 80 mph faster than another. While one travels 1750 miles, the other travels 950 miles. find the speed of each plane.
\n" ); document.write( "--------------------
\n" ); document.write( "faster plane DATA:
\n" ); document.write( "rate = x + 80 mph ; distance = 1750 ; time = 1750/(x+80) hrs.
\n" ); document.write( "-----------
\n" ); document.write( "slower plane DATA:
\n" ); document.write( "rate = x mph ; distance = 950 ; time = 850/x hrs
\n" ); document.write( "------
\n" ); document.write( "Equation::
\n" ); document.write( "time = time
\n" ); document.write( "1750/(x+80) = 850/x
\n" ); document.write( "-----------------------
\n" ); document.write( "1750x = 850x + 80*850
\n" ); document.write( "--------------------------
\n" ); document.write( "900x = 80*850
\n" ); document.write( "------
\n" ); document.write( "x = 75.56 mph
\n" ); document.write( "x+80 = 155.56 mph
