Plane II 400 mph
\n" ); document.write( "Plane I = 300 mph\r
\n" ); document.write( "\n" ); document.write( "moving in same direction
\n" ); document.write( "so subtract the speeds
\n" ); document.write( "400-300 = 100 mph\r
\n" ); document.write( "\n" ); document.write( "distance = 350 miles\r
\n" ); document.write( "\n" ); document.write( "t= d/r
\n" ); document.write( "catch up time = 350/100\r
\n" ); document.write( "\n" ); document.write( "= 3.5 hours
\n" ); document.write( "
