A train 240m long takes 24 secs to cross a man running at 10km/hr in the same direction as the train. The speed of the train is.
\n" ); document.write( "**
\n" ); document.write( "let x=speed of train
\n" ); document.write( "240m/24sec=240m/24sec*km/1000m*3600sec/hr
\n" ); document.write( "=240*3600/24*1000 km/hr
\n" ); document.write( "=36km/hr (difference in speed between train and runner)
\n" ); document.write( "speed of train=10+36=46 km/hr
\n" ); document.write( "
\n" );
