A train leaves Danville Junction and travels north at a speed of 75km/hr.
\n" ); document.write( "Two hours later, an express train leaves on a parallel track and travels north at 125km/hr.
\n" ); document.write( " How far from the station will they meet?
\n" ); document.write( "--------------
\n" ); document.write( "Regular train DATA:
\n" ); document.write( "Time = x hrs ; rate = 75 km/hr ; distance = r*t = 75x km
\n" ); document.write( "-----------------------
\n" ); document.write( "Express train DATA:
\n" ); document.write( "Time = x-2 hrs ; rate = 125 km/hr ; distance = rt = 125(x-2) km
\n" ); document.write( "-------------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "distance = distance
\n" ); document.write( "75x = 125(x-2)
\n" ); document.write( "75x = 125x-250
\n" ); document.write( "50x = 250
\n" ); document.write( "x = 5 hrs (time of the regular train)
\n" ); document.write( "75x = 375 km (distance the regular train traveled=distance express traveled)
\n" ); document.write( "================
