This gives you that they are travelling towards each other at 90km/hr.\r \n" ); document.write( "\n" ); document.write( "Now use the equation for speed time and distance:\r \n" ); document.write( "\n" ); document.write( "distance = speed * time \n" ); document.write( "time = distance/speed \n" ); document.write( "=360/90 \n" ); document.write( "=4 hrs \n" ); document.write( " \n" ); document.write( " |
