Remember D = RT, distance = rate*time.
\n" ); document.write( "Let us call his time for the first trip, t. Thus the time on his return car trip is t - 2. The distances are the same so we have
\n" ); document.write( "25t = 75(t - 2)
\n" ); document.write( "25t = 75t - 150
\n" ); document.write( "-50t = -150
\n" ); document.write( "t = 3
\n" ); document.write( "So the distance is 25t or 75 miles.
\n" ); document.write( "
\n" );
