You can put this solution on YOUR website!
let the speed of the train be x km/h\r
\n" ); document.write( "\n" ); document.write( "distance between AB = 45/60 * x\r
\n" ); document.write( "\n" ); document.write( "speed decreased by 5 km/h\r
\n" ); document.write( "\n" ); document.write( "speed = (x-5)\r
\n" ); document.write( "\n" ); document.write( "d= (x-5) * 48/60 km\r
\n" ); document.write( "\n" ); document.write( "But d is same \r
\n" ); document.write( "\n" ); document.write( "so\r
\n" ); document.write( "\n" ); document.write( "45/60 * x = 48/60*(x-5)\r
\n" ); document.write( "\n" ); document.write( "45x=48x-240\r
\n" ); document.write( "\n" ); document.write( "3x=240
\n" ); document.write( "/3
\n" ); document.write( "x= 80\r
\n" ); document.write( "\n" ); document.write( "speed of train is 80 km/h
\n" ); document.write( "time = 45 minutes = 3/4 hour\r
\n" ); document.write( "\n" ); document.write( "d=rt\r
\n" ); document.write( "\n" ); document.write( "80*3/4\r
\n" ); document.write( "\n" ); document.write( "=60 km\r
\n" ); document.write( "\n" ); document.write( "Distance between A & B = 60 km\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
