On a trip across the Grand Canyon in Arizona, a group traveled one-third
\n" ); document.write( "the distance by mule, 6 kilometers by boat, and one-half the distance by foot.
\n" ); document.write( " How long was the trip?
\n" ); document.write( ":
\n" ); document.write( "Let d = the total distance of the trip
\n" ); document.write( ":
\n" ); document.write( "d = Mule + boat + foot
\n" ); document.write( "d = $\"1%2F3\"$ d + 6 + $\"1%2F2\"$ d
\n" ); document.write( "multiply by 6 to clear the denominators, results
\n" ); document.write( "6d = 2d + 6(6) + 3d
\n" ); document.write( "6d = 5d + 36
\n" ); document.write( "6d - 5d = 36
\n" ); document.write( "d = 36 km trip
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check; find the distance at each stage of the trip
\n" ); document.write( " $\"1%2F3\"$ (36) = 12
\n" ); document.write( " $\"1%2F2\"$ (36) = 18
\n" ); document.write( "boat dist = 6
\n" ); document.write( "---------------------
\n" ); document.write( "total distance: 36 \n" ); document.write( "

\n" );
