Two trains started a journey at the same time from two places 300km apart.
\n" ); document.write( " They travelled towards each other, one train travelling twice as fast as the other.
\n" ); document.write( " They met 3/2 hours after they started, find the speed of the trains
\n" ); document.write( ":
\n" ); document.write( "let s = speed of the slower train
\n" ); document.write( "then
\n" ); document.write( "2s = speed of the faster
\n" ); document.write( ":
\n" ); document.write( "When the trains meet the total of their distances = 300 km
\n" ); document.write( "Write a distance equation; dist = time * speed
\n" ); document.write( "1.5(s) + 1.5(2s) = 300
\n" ); document.write( "1.5s + 3s = 300
\n" ); document.write( "4.5s = 300
\n" ); document.write( "s = 300/4.5
\n" ); document.write( "s = 66 $\"2%2F3\"$ km/hr is speed of the slower train
\n" ); document.write( "and
\n" ); document.write( "2(66 $\"2%2F3\"$ ) = 133 $\"1%2F3\"$ km is the speed of the faster train
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this, find the actual dist each train traveled
\n" ); document.write( "1.5(66.67) = 100 km
\n" ); document.write( "1.5(133.33) = 200 km
\n" ); document.write( "-----------------------
\n" ); document.write( "total distance 300 km \n" ); document.write( "

\n" );
