Freight train A goes from point A to point B at 40 miles per hour.
\n" ); document.write( "distance = x miles ; rate = 40 mph ; time = x/40 hrs.
\n" ); document.write( "------------------------------------------------------------\r

\n" ); document.write( "distance = x miles ; rate = 30 mph ; time = x/30 hrs
\n" ); document.write( "---------------------------------------------\r
\n" ); document.write( "\n" ); document.write( "What is the distance from point A to point B?
\n" ); document.write( "Equation:
\n" ); document.write( "slower train - faster train = 2 hrs
\n" ); document.write( "x/30 - x/40 = 2 hrs
\n" ); document.write( "40x - 30x = 2*40*30
\n" ); document.write( "10x = 2*40*30
\n" ); document.write( "x = 240 miles
