If the speed of the passenger train is 25 mi/hr faster than the speed of the freight train, find the speed of each. Make sure in the right hand column you give the speeds of each train.\r

Algebra.Com's Answer #45892 by 303795(602)![]() ![]() ![]() You can put this solution on YOUR website! Freight train speed =x so the speed of the passenger train is x + 25 \n" ); document.write( "Time = distance/speed so \n" ); document.write( " \n" ); document.write( "Multiply each side by x \n" ); document.write( " \n" ); document.write( "Multiply each side by (x+25) \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Subtract 200x from each side \n" ); document.write( " \n" ); document.write( "x=5000/125 \n" ); document.write( "=40 mile per hour and the passenger train speed is 65 miles per hour\r \n" ); document.write( "\n" ); document.write( "(A non algebra method would take the idea that the passenger train travels an extra 125 miles and is 25 miles per hour faster so the journey would take 5 hours. The speeds would therefore be 325/5 = 65 miles per hour and 200/5=40 miles per hour) \n" ); document.write( " |
