8. A train leaves Toronto for Montreal at the same time as another train leaves
\n" ); document.write( " Montreal for Toronto. The cities are 500 km apart. The trains pass each other
\n" ); document.write( " 2 h later. The train from Montreal is traveling 50 km/h faster than the one
\n" ); document.write( " from Toronto. Assume you mean,\"How far from Toronto do the trains pass each other?\"
\n" ); document.write( ":
\n" ); document.write( "Let s = the speed of the train from Toronto
\n" ); document.write( "then
\n" ); document.write( "(s+50) = the speed of the train from Montreal
\n" ); document.write( ":
\n" ); document.write( "When the two trains meet, they will have traveled a total of 500 mi
\n" ); document.write( "Write a distance equation; dist = time * speed
\n" ); document.write( "2(s+50) + 2s = 500
\n" ); document.write( "2s + 100 + 2s = 500
\n" ); document.write( "2s + 2s = 500 - 100
\n" ); document.write( "4s = 400
\n" ); document.write( "s = 100 km/hr is the Toronto train
\n" ); document.write( "in 2 hrs the the Toronto train will be 200 km from Toronto
\n" ); document.write( "and
\n" ); document.write( "check it by finding that 2(150) = 300 km is the Montreal train from Montreal \n" ); document.write( "
\n" );
