\n" );
document.write( "Hi, 
\n" );
document.write( "d = r*t
\n" );
document.write( "Let t represent the time the express train travels. 
\n" );
document.write( "then (t + 1.25hr) is the time the local commuter travels (1hr and 15min = 1.25hr)
\n" );
document.write( "Distance will be the same when the express train catches up to the local commuter***
\n" );
document.write( "36mph(t + 1.25hr)= 81mph*t
\n" );
document.write( "36*1.25hr = 45mph*t
\n" );
document.write( "1 hr = t, the time the express train travels and will catch up to the local commuter\r
\n" );
document.write( "\n" );
document.write( "checking our answer
\n" );
document.write( "36mph*2.25hr = 81mph*1hr = 81mi\r
