They meet in 4 hours. If one train is 15 mph faster than the other, find the speed of each train. \n" ); document.write( "----------- \n" ); document.write( "Slower train DATA: \n" ); document.write( "time = 4 hrs ; rate = x mph ; distance = 4x miles \n" ); document.write( "------ \n" ); document.write( "Faster train DATA: \n" ); document.write( "time = 4 hrs ; rate = x+15 mph ; distance = 4(x+15) miles \n" ); document.write( "-------------------------- \n" ); document.write( "Equation: \n" ); document.write( "4x + 4(x+15) = 380 \n" ); document.write( "4x + 4x + 60 = 380 \n" ); document.write( "8x = 320 \n" ); document.write( "x = 40 mph (slower train rate) \n" ); document.write( "x+15 = 55 mph (faster train rate) \n" ); document.write( "====================================== \n" ); document.write( "Stan H. \n" ); document.write( "=============== \n" ); document.write( " |
