Algebra.Com's Answer #376812 by mananth(16946)![]() ![]() You can put this solution on YOUR website! Length of train I = 230 ft. \n" ); document.write( "length of second train = 210 ft.\r \n" ); document.write( "\n" ); document.write( "Length of both trains = 230 +210 = 440 ft. \n" ); document.write( "This is the distance to be traveled so that they cross each other completely. \n" ); document.write( "1 mile = 5280 ft \n" ); document.write( "440 ft = 440/5280 = 0.083 miles\r \n" ); document.write( "\n" ); document.write( ".. \n" ); document.write( "The trains are moving towards each other. add up speeds\r \n" ); document.write( "\n" ); document.write( "50 + 60 = 110 mph \r \n" ); document.write( "\n" ); document.write( "time = distance / speed\r \n" ); document.write( "\n" ); document.write( "time = 44/528 * 1/110\r \n" ); document.write( "\n" ); document.write( "Time = 1/1320 hours\r \n" ); document.write( "\n" ); document.write( "= 1/1320 * 3600 \n" ); document.write( "= 2.73 seconds \n" ); document.write( "They wil take 2.73 second to cross each other \n" ); document.write( " |
