A train leaves the station a 6:00 PM traveling west at 80 mi/h. On a parallel track, a second train leaves the station 3 hours later traveling west at 100 mi/h. At what time will the second train catch up with the first?
\n" ); document.write( "-------------------
\n" ); document.write( "Early train DATA:
\n" ); document.write( "rate = 80 mph ; time = x hrs.; distance = 80x miles
\n" ); document.write( "---------------------
\n" ); document.write( "Later train DATA:
\n" ); document.write( "rate = 100 mph ; time = x-3 hrs ; distance = 100(x-3) miles
\n" ); document.write( "-------------------
\n" ); document.write( "Equation:
\n" ); document.write( "80x = 100x - 300
\n" ); document.write( "-20x = -300
\n" ); document.write( "x = 15 hrs
\n" ); document.write( "------------------
\n" ); document.write( "Time: 6:00PM + 15 hrs = 9:00AM
\n" ); document.write( "===================================
