Gena walked 160 feet in 40 seconds on a moving walkaway.
\n" ); document.write( " Against the walkaway, she was able to walk the same distance in 80 seconds.
\n" ); document.write( " What is the rate at which Gena walked, and what is the rate of the walkaway?
\n" ); document.write( ":
\n" ); document.write( "Let g = Gena's walking rate (ft/sec
\n" ); document.write( "Let w = the walkway rate
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation for each scenario; dist = time * speed
\n" ); document.write( ":
\n" ); document.write( "40(g+w) = 160
\n" ); document.write( "and
\n" ); document.write( "80(g-w) = 160
\n" ); document.write( "we can simplify both these equations, divide the 1st one by 40, the 2nd one by 80
\n" ); document.write( "g + w = 4
\n" ); document.write( "g - w = 2
\n" ); document.write( "------------addition eliminates w, find g
\n" ); document.write( "2g = 6
\n" ); document.write( "g = 3 ft/sec is Gina's walking rate
\n" ); document.write( "and
\n" ); document.write( "3 + w = 4
\n" ); document.write( "w = 4 - 3
\n" ); document.write( "w = 1 ft/sec is the walkway rate
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "See if that flies:
\n" ); document.write( "40(3 + 1) = 160
\n" ); document.write( "and
\n" ); document.write( "80(3 -1) = 80
\n" ); document.write( "
\n" );
