a passenger train leaves a train depot 1 hr after a freight train leaves the same depot. the freight train is traveling 15 mph slower than the passenger train. find the rate of each train if the passenger train over takes the freight train in 3 hrs.
\n" ); document.write( "
Let speed of passenger train be S
\n" );
document.write( "Then speed of freight train = S - 15  
\n" );
document.write( "We then get the following DISTANCE equation: 3S = 4(S - 15)
\n" );
document.write( "3S = 4S - 60
\n" );
document.write( "3S - 4S = - 60
\n" );
document.write( "- S = - 60
\n" );
document.write( "S, or speed of passenger train = \"highlight_green%28matrix%281%2C4%2C+%28-+60%29%2F%28-+1%29%2C+or%2C+60%2C+mph%29%29\" 
\n" );
document.write( "Speed of freight train: \"highlight_green%28matrix%281%2C4%2C+60+-+15%2C+or%2C+45%2C+mph%29%29\" \n" );
