Two trains are 330 miles apart, and their speeds differ by 20 mph. They travel toward each other and meet in 3 hrs. Find the speed of each train.
\n" ); document.write( "-------------------------
\n" ); document.write( "Let the speed of one train be \"x\" mph.
\n" ); document.write( "Then the speed of the 2nd train is \"x+20\"
\n" ); document.write( "----
\n" ); document.write( "And the combined speed of the 2 trains is x + x+20 = 2x+20 mph
\n" ); document.write( "------------------
\n" ); document.write( "Equation:
\n" ); document.write( "distance = rate *time
\n" ); document.write( "330 = (2x+20)*3
\n" ); document.write( "110 = 2x+20
\n" ); document.write( "2x = 90
\n" ); document.write( "x = 45 mph (speed of one train)
\n" ); document.write( "x+20 = 65 mph (speed of the other train)
\n" ); document.write( "===========================================
