An aircraft carrier made a trip to Guam and back.
\n" ); document.write( " The trip there took three hours and the trip back took four hours.
\n" ); document.write( " It averaged 6 km/h on the return trip.
\n" ); document.write( " Find the average speed of the trip there.
\n" ); document.write( ":
\n" ); document.write( "let s = speed there
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation; dist = speed * time
\n" ); document.write( ":
\n" ); document.write( "Dist there = dist back
\n" ); document.write( "3s = 4(6)
\n" ); document.write( "3s = 24
\n" ); document.write( "s = \"24%2F3\"
\n" ); document.write( "s = 8 km/h, av speed there \n" ); document.write( "
\n" );
