the distance traveled by both is same when one catches up with the other.
\n" ); document.write( "Let them meet at distance x
\n" ); document.write( "Plane speed= 192 mph , starts at
\n" ); document.write( "Jet speed= 960 mph starts at
\n" ); document.write( "
\n" ); document.write( "Time difference between the starting of the two= 2.00 hours
\n" ); document.write( "
\n" ); document.write( "Time taken by Plane = X / 192
\n" ); document.write( "Time taken by Jet = X / 960
\n" ); document.write( "
\n" ); document.write( "X / 192 - X / 960 = 2
\n" ); document.write( "
\n" ); document.write( "LCD - 960
\n" ); document.write( "Multiply equation by 960 960
\n" ); document.write( "
\n" ); document.write( "5 x - 1 x = 1920
\n" ); document.write( "4 x = 1920
\n" ); document.write( "/ 4
\n" ); document.write( "x= 480 miles
\n" ); document.write( "Jet speed= 960 mph
\n" ); document.write( "Distance = 480 miles
\n" ); document.write( "Time taken = 480 / 960
\n" ); document.write( "Time taken = 0.5 hours
\n" ); document.write( " \n" ); document.write( "

\n" );
