Two trains are 330 miles apart, and their speeds differ by 20 mph. Find the speed of each train if they are traveling toward each other and will meet in 3 hours.
\n" ); document.write( "-------------------
\n" ); document.write( "1st Train DATA:
\n" ); document.write( "distance: x miles ; time = 3 hrs ; rate = x/3 hrs
\n" ); document.write( "--------------------------------------------------
\n" ); document.write( "2nd Train DATA:
\n" ); document.write( "distance: (330-x) miles ; time = 3 hrs ; rate = (330-x)/3= 110-(x/3) hrs
\n" ); document.write( "------------------------------------------------
\n" ); document.write( "rate1 - rate2 = 20
\n" ); document.write( "(x/3) - [110-(x/3)] = 20
\n" ); document.write( "(2/3)x = 20 + 110
\n" ); document.write( "(2/3)x = 130
\n" ); document.write( "x = (3/2)130
\n" ); document.write( "x = 195 miles (distance traveled by 1st Train)
\n" ); document.write( "speed of Train1 = 195/3 = 65 mph
\n" ); document.write( "----------------
\n" ); document.write( "speed of Train2 = (330-195)/3 = 45 mph
\n" ); document.write( "===============================================
