steve traveled 600 miles at a certain speed. had he gone 20mph faster, the trip would have taken 1 hour less. Find the speed of his vehicle.\r
\n" ); document.write( "\n" ); document.write( "1st trip Data:
\n" ); document.write( "distance = 600 miles; Rate= x mph; Time= 600/x hrs.\r
\n" ); document.write( "\n" ); document.write( "2nd trip Data:
\n" ); document.write( "Distance=600 miles;Rate=(x+20)mph; Time=600/(x+20)\r
\n" ); document.write( "\n" ); document.write( "EQUATION:
\n" ); document.write( "1st trip time = 2nd trip time +1 hr.
\n" ); document.write( "600/x = 600/(x+20) + 1\r
\n" ); document.write( "\n" ); document.write( "600(x+20)=600x+x(x+20)
\n" ); document.write( "600x+12000=600x+x^2+20x
\n" ); document.write( "x^2+20x-12000=0
\n" ); document.write( "(x+120)(x-100)=0
\n" ); document.write( "x=100 mph (Speed of Steve's vehicle on the 1st trip)
