Two high speed trains are 380 miles apart and traveling toward each other. 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)
