The speed of train A is 12 mph slower than the speed of train B. Train A travels 190 miles in the same time it takes Train B 250 miles. Find the speed of each train.
\n" ); document.write( "---------------------
\n" ); document.write( "Train B DATA:
\n" ); document.write( "rate = x mph ; distance = 250 miles ; time = d/r = 250/x hrs
\n" ); document.write( "--------------------------
\n" ); document.write( "Train A DATA:
\n" ); document.write( "rate = x-12 mph ; distance = 190 miles ; time = d/r = 190/(x-12) hrs
\n" ); document.write( "===============================
\n" ); document.write( "Equation:
\n" ); document.write( "time A = time B
\n" ); document.write( "190/(x-12) = 250/x
\n" ); document.write( "190x = 250(x-12)
\n" ); document.write( "190x - 250x = -12*250
\n" ); document.write( "-60x = -12*250
\n" ); document.write( "x = 50 mph (Train B speed)
\n" ); document.write( "x-12 mph = 38 mph (Train A speed)
\n" ); document.write( "==================================
