The speed of a passenger train is 18 mph faster than the speed of a freight train. The passenger train travels 320 miles in the same time it takes the freight train to travel 230 miles. What is the speed of each train?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let speed of freight train be x mph\r
\n" ); document.write( "\n" ); document.write( "freight train travels 230 miles\r
\n" ); document.write( "\n" ); document.write( "time taken = 230/x
\n" ); document.write( ".
\n" ); document.write( "passenger train speed will be x+18 mph\r
\n" ); document.write( "\n" ); document.write( "time taken = 320/x+15\r
\n" ); document.write( "\n" ); document.write( "these two times are equal\r
\n" ); document.write( "\n" ); document.write( "230/x = 320 / x+18\r
\n" ); document.write( "\n" ); document.write( "230(x+18)=320*x\r
\n" ); document.write( "\n" ); document.write( "230x +4140 =320x\r
\n" ); document.write( "\n" ); document.write( "-90x=-4140\r
\n" ); document.write( "\n" ); document.write( "x= 46 mph the speed of the freight train\r
\n" ); document.write( "\n" ); document.write( "46+18 = 64 mph is the speed of the passenger train\r
