An aircraft carrier left Diego Garcia and traveled toward St. Vincent at an average speed of 12 km/h.\r
\n" ); document.write( "\n" ); document.write( "Let the time taken to meet be x\r
\n" ); document.write( "\n" ); document.write( "distance travelled = 12x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " A container ship left one hour later and traveled in the same direction but with an average speed of 15 km/h.\r
\n" ); document.write( "\n" ); document.write( "one hour later
\n" ); document.write( "time = (x-1) hours\r
\n" ); document.write( "\n" ); document.write( "distance travelled = 15(x-1)\r
\n" ); document.write( "\n" ); document.write( "distance travelled by both when they meet is same\r
\n" ); document.write( "\n" ); document.write( "15(x-1) = 12x\r
\n" ); document.write( "\n" ); document.write( "15x-12x = 15\r
\n" ); document.write( "\n" ); document.write( "3x= 15
\n" ); document.write( "x= 5 \r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
