trains a and b are traveling the same direction on parallel tracks.
\n" ); document.write( "train a is traveling at 100mph and train b is traveling at 120mph.
\n" ); document.write( "train a passes a station at 10:25am.if train b passes the same station at 10:40am,
\n" ); document.write( "what time will train b catch up to train a?
\n" ); document.write( "------------
\n" ); document.write( "Train A DATA:
\n" ); document.write( "Rate = 100 mph ; time = x hrs ; distance = rt = 100x miles
\n" ); document.write( "---------------------
\n" ); document.write( "Train B DATA:
\n" ); document.write( "Rate = 120 mph ; time = x-(1/4) hr ; distance = rt = 120x - 30 miles
\n" ); document.write( "-----------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "distance A = distance B
\n" ); document.write( "100x = 120x - 30
\n" ); document.write( "20x = 30
\n" ); document.write( "x = 3/2 hrs
\n" ); document.write( "---------------
\n" ); document.write( "B catches A at 10:25 + 1 1/2 hrs = 11:55
\n" ); document.write( "=======================
