\n" ); document.write( "\n" ); document.write( "Two trains are 500 miles apart when they first enter a collision course. If, after two hours, the distance between them is 300 miles and one train goes 20 mph faster than the other, find the speed of the faster train.

Let faster train’s speed be S
\n" );
document.write( "Then slower train’s speed = S – 20
\n" );
document.write( "At 1st they were 500 miles apart, but after 2 hours, they were 300 miles apart, which means that in 2 hours they covered 200 (500 – 300) miles
\n" );
document.write( "We then get the following DISTANCE equation: 2S + 2(S – 20) = 200
\n" );
document.write( "2S + 2S – 40 = 200
\n" );
document.write( "4S – 40 = 200
\n" );
document.write( "4S = 240
\n" );
document.write( "S, or speed of faster train =  \n" );
document.write( "

\n" );
