The distance between delhi and meerut is 75 km.Two trains at a speed of 100km/hr & 80km/hr leave the two stations at 8 am towards eachother.At what time will they pass eachother\r
\n" ); document.write( "\n" ); document.write( "Let the distance they meet after start be x\r
\n" ); document.write( "\n" ); document.write( "d= rt Or t= d/r\r
\n" ); document.write( "\n" ); document.write( "time taken by one train = x/100
\n" ); document.write( "time taken by other train = (75-x)/80\r
\n" ); document.write( "\n" ); document.write( "These two times are same\r
\n" ); document.write( "\n" ); document.write( "x/100 = (75-x)/80\r
\n" ); document.write( "\n" ); document.write( "80x=100(75-x)\r
\n" ); document.write( "\n" ); document.write( "80x=7500-100x\r
\n" ); document.write( "\n" ); document.write( "80x+100x=7500
\n" ); document.write( "180x= 7500\r
\n" ); document.write( "\n" ); document.write( "x= 41.67 km\r
\n" ); document.write( "\n" ); document.write( "time they meet = 41.67/100
\n" ); document.write( "=0.42 hours= 25 minutes\r
\n" ); document.write( "\n" ); document.write( "they will cross at 8:25 AM\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
