Algebra.Com's Answer #256608 by mananth(16946)![]() ![]() You can put this solution on YOUR website! Two train are 532 miles apart and are traveling toward each other. One train is traveling 9 mph faster than the other train. The trains pass each other in 4 hours. Fine the speed of each train. \n" ); document.write( ".. \n" ); document.write( "let one train's speed be x \n" ); document.write( "other speed = x+9 \n" ); document.write( ".. \n" ); document.write( "since they are travelling towards each other the effective speed =2x+9 mph \n" ); document.write( "distance = 532 miles \n" ); document.write( "time = distance/speed \n" ); document.write( "532/(2x+9)=4 \n" ); document.write( "532=4*(2x+9) \n" ); document.write( "532=8x+36 \n" ); document.write( "8x=532-36 \n" ); document.write( "8x=496 \n" ); document.write( "/8 \n" ); document.write( "x=62 mph speed of one train \n" ); document.write( "other train speed = 62+9 = 71 mph \n" ); document.write( "... \n" ); document.write( "m.ananth@hotmail.ca \n" ); document.write( " \n" ); document.write( " |
