A plane takes 10 hours less to travel 1200 km than a train. If the plane travels six times as fast as
\n" ); document.write( "the train, what was the speed of the plane?
\n" ); document.write( "-----------------
\n" ); document.write( "P = plane's speed, T = train's speed in mi/hr
\n" ); document.write( "---
\n" ); document.write( "P = 6T
\n" ); document.write( "\"1200%2FP+=+1200%2FT+-+10\"
\n" ); document.write( "Sub for P
\n" ); document.write( "\"1200%2F%286T%29+=+1200%2FT+-+10\"
\n" ); document.write( "Multiply thru by 6T
\n" ); document.write( "\"1200+=+7200+-+60T\"
\n" ); document.write( "etc
\n" ); document.write( "
\n" );
